New approach to quantum dots may bolster electronics

24 Nov '21
Researchers at the Moscow Institute of Physics and Technology (MIPT, aka Phystech) in collaboration with colleagues from the Institute of Problems of Chemical Physics based in Chernogolovka outside Moscow are offering a simple and convenient way of obtaining quantum dots of certain sizes and properties through chemical aging. The method may help simplify and cut the cost of making solar cells, TV sets or fire detectors.

The aging of crystals is a widely used scientific term for controlled change of materials characteristics as certain time lasts.

We have developed a solution that would enable experimenters who have 10 nanometer sized quantum dots to age them down to 8 nanometers tomorrow, to 6 nanometers two days from now, and so on and so forth. In the process, their absorption properties would change from 2 micrometers to 1.8 micrometers with the first aging and down to 1.5 micrometers with the next. That means that a single test tube, a very short time and an array of very simple operations are enough to get colloidal quantum dots of desired sizes and properties, said Vladimir Razumov who runs MIPTs quantum-sized photonics lab.
