材一216.
Han Jiaying and Chen Wanqing went to Zhangjiang. Only Wu Feifei, Duan Yun, Tian Qing and the new Sun Wo were in the office.
After more than a week, Sun Wo has also been integrated into the research team. His posture is very low. Everyone is called Senior Brother and Senior Sister, and even Han Jiaying is called Senior Sister.
Sun Wo’s family is a native of the magic city. He lives not far from the school. Because he came to Teacher Wei’s joint training, he does not have a dormitory. He rides a bicycle to and from school and home every day. About half an hour.
One of his hobbies is stock speculation. It is said that he entered the stock market with 10,000 yuan four years ago, and now there is still 10,100 yuan and two cents. According to the rule of one win, two draws and seven losses, he is more than A master of 90% of shareholders.
Another hobby, or specialty, is that he passed the Neon Language N1 exam. It is said that he was annoyed to learn neon language because he couldn't wait for the sinicization of Fan Opera and it was too painful to eat raw meat.
Sun Wo was arranged by Teacher Wei to make Wu Feifei a perovskite, so Xu Qiu and him did not have much intersection.
Today Xu Qiu’s task is mainly to debug the TRPL instrument, but now Qiu Heming has not come here, he is doing his own experiments and also preparing some samples along the way.
The sample preparation requirements this time are not as high as the previous ones at Sioux City University. The sample size is any size between 1 cm by 1 cm and 5 cm by 5 cm.
According to Xu Qiu's usual habits, a rectangular glass slide was divided into three equal parts with a glass knife, and a square glass slide with a side length of about 2.5 cm was obtained as a base.
As for the choice of samples, he chose P3HT, PCE10, two standard samples, as well as his own PCE11 series, and the 3D-PDI series that he just got.
In addition to the organic samples, Teacher Wei also asked Feifei Wu to prepare some samples of perovskite.
Although perovskite photovoltaic is still an emerging field, there are not many research groups using TRPL instruments for characterization, but it does not mean that research in this area is not important, but for the time being, researchers are still in the efficiency sprint stage.
If we can get a head start in this area in advance, there is still the possibility of winning big articles.
This is also the reason why Mr. Wei made up his mind to purchase the instrument very quickly. Not only can it be used in the organic field, perovskite can be used, including quantum dots, which fits well with the research direction of the research group.
...
At around two o'clock in the afternoon, Xu Qiu and Tian Qing were summoned by Teacher Wei to his office.
There are two strange men in the room sitting on the sofa where Teacher Wei entertains the guests. In the middle is a mature middle-aged uncle who looks quite capable. He holds a disposable paper cup in his hand and contains hot tea. The other is a young guy, who looks like a hard-working brother.
There are also two cardboard boxes on the ground, one of which is an ordinary yellow-brown cardboard box, and the other is more delicate, with the words "HORIBA" printed on it and "Transient Fluorescence Spectrometer", which looks like a TRPL instrument.
Wei Xingsi introduced the two sides: "This is Dr. Qiu Heming," and "These two are my two students, Xu Qiu and Tian Qing."
"Hello."
"Hello, Dr. Qiu."
Qiu Heming got up, proactively extended his hands to Xu Qiu and Tian Qing, shook hands in a courteous manner, and then said:
"Ms. Wei, let's start now, where will the instrument be installed?"
"It's in the utility room on my side." Wei Xingsi waved his hand and took a step ahead, and everyone followed him.
The utility room is not big, only a few square meters. There is a sink inside and an empty table. The table is obviously just polished and shiny.
Qiu Heming roughly estimated the area of ​​the table, nodded and said: "This is ok, there is enough space, Xiao Liu, you go and bring the instrument over."
"Good." Xiao Liu received the instruction and quickly opened the ordinary carton. A black painted metal sample compartment was revealed. He picked up the sample compartment, entered the utility room, and placed it carefully. On the table.
Afterwards, he disassembled another carton box in the same way and placed four set-top box-like instruments next to the sample compartment.
Wei Xingsi only watched for a while before returning to his desk, leaving Xu Qiu and Tian Qing in charge of supervision.
Qiu Heming began to assemble the instrument.
Halfway through the installation, he stopped abruptly and said, "We will need a computer for the next test."
Xu Qiu muttered to himself: ‘It’s really a pitfall that selling instruments is not worthy of computers. ’
‘However, this seems to be a practice in the industry. The computers in the laboratory were bought by Teacher Wei later. Because the price was more than 1,000, they were all regarded as fixed assets. They were theoretically owned by the state and they only had the right to use them. ’
"Use mine first." Xu Qiu said helplessly. Tian Qing next to him showed no signs of action.
Wei Xingsi heard their conversation and took the initiative: "Make do with it first, and then I will buy a new computer."
Xu Qiu responded, and returned to 216 to take his laptop.
Fortunately, the battery of the laptop he is currently using is not broken. Before, there was a laptop with a battery life of only 5 seconds. It must be plugged in to use it. It is no different from a desktop computer.
When Xu Qiu returned to 218 again, Qiu Heming had completed the installation of the instrument. Of course, he just connected the cable. Optical instruments and debugging the optical path were the troublesome things.
Qiu Heming took out a USB flash drive from his pocket and inserted it into Xu Qiu's computer.
Two softwares are installed, one is the test software, the other is the data analysis software, and a serial number is entered to activate the two software.
During the software installation, Xu Qiu was observing the entire set of TRPL instruments in front of him.
In the middle of the sample compartment is a sample table, which can be used for various sample tests. It can be used for clamping pieces, or directly loading cuvettes, and even a low temperature device. This is a supplementary request made by Teacher Wei later.
For this reason, Qiu Heming and the others specially made two types of cover plates for the sample chambers, one is a solid square cover, and the other is a round cover at the center. The size is based on the cryogenic device in the laboratory. of.
The sample chamber is square, with four sides, and each side has a round hole. A laser or signal detection device can be installed on the round hole.
At present, only three have been installed, two of which are lasers with picosecond lasers of 465 and 695 nanometers, and the other is a detector that can detect light signals in the visible and near-infrared range.
The optical paths of the two lasers are perpendicular to the detector respectively. If they are not perpendicular, the laser is directly connected to the detector, and the detector may be directly GG.
In the future, if necessary, another detector can be installed to detect light signals in the far infrared range.
The three devices on the sample compartment are respectively connected to three of the four "set-top boxes" next to them through finger-thick data cables, and they have laser and detector switches.
These three "set-top boxes" are all connected to the last "set-top box", which is the main console.
The main console is then connected to the computer, and the entire instrument is controlled by computer software.
In addition to these main devices, in the sample chamber, the laser and detector are each equipped with two lenses to focus the light path, and there are also slots for installing other optical components.
For example, placing a "bandpass" element that only allows light near a given wavelength to pass through in front of the laser light path can improve the purity of the laser.
For another example, the use of "high-pass" and "low-pass" elements that only allow light above a given wavelength to pass through can eliminate the mutual influence of the fluorescence signals of the multi-component system.
In addition, there are ND filters for reducing light intensity and so on.
Xu Qiu did not forget to copy Qiu Heming's skills. His PL and TRPL proficiency were 30% for Tier 5 and 20% for Tier 5 respectively. It seems that he is an experienced salesman.
Throughout the afternoon, Xu Qiu and Tian Qing were dragged by Qiu Heming, and they have been debugging the instrument and testing the organic and perovskite samples they prepared.
After all, it's nearly 200,000 instruments, so sloppy.
The results show that the cryogenic device in the laboratory can be put in tightly;
The optical components brought by Qiu Heming can be used normally;
After the cover on the sample compartment is covered, the sample compartment does not leak light;
The operating software and data processing software are both easy to use, but the operating software now only has a 30-day trial period, because the genuine authorization code is bound to the computer. Now Xu Qiu’s computer is only temporarily in use, Qiu Heming said that the computer will be fixed afterwards , Will provide a genuine authorization code;
Of course, the most important thing is that the instrument data is reliable and repeatable.
The basis for evaluating this is the test result of the P3HT standard sample. The result tested with this instrument is basically consistent with the result of the literature.
One advantage of a standard sample such as P3HT that has been studied for a long enough time is that as long as you can think of a characterization method, there are basically more than one literature data for reference.
This is also the meaning of the standard sample.
At about five o'clock, the equipment was finally debugged.
Qiu Heming declined Teacher Wei's polite remarks for dinner, and left with his younger brother.
In the evening, Xu Qiu used the TRPL instrument to test all the samples~EbookFREE.me~ and processed the data briefly, and then reported the results to Teacher Wei.
On the organic side, no exaggerated conclusions have been drawn for the time being.
After all, the new system has only one 3D-PDI. The data of testing and individual components and blended films can only show that the fluorescence quenching efficiency is not low after blending.
The data of a single molecule does not have much meaning. Only when the new structure is optimized can be compared with each other.
Tian Qing helped deal with the data on Wu Feifei's perovskite, and her ammonium chloride and calcium chloride additive system seemed to have something new.
But Xu Qiu didn't pay too much attention. He took a good time and squatted on the school bus like yesterday.
Then, the adultery between the two was discovered by the senior sister.
