Experts discuss colloidal optoelectronics at the 9th Congress of the Photonics Russian Technology Platform

31 / 03 / 2021

The Photonics. World of Lasers and Optics 2021 accompanying programme is of great interest for the scientific and industrial community and experts. It covers a range of the most important issues of fundamental significance for wide application of state-of-the-art laser technologies, optical and optoelectronic equipment in the key industries and social sphere.

The 9th Congress of the Photonics Russian Technology Platform became one of the key events of Photonics 2021. A plenary session was held today. It began with the awarding of honorary diplomas by the Laser Association to the winners of the best developments that had been brought to market over the last two years. According to Ivan Kovsh, President of the Association, this awarding reflects a very high level of developments, which are subjected to serious expertise and the selection of the best of them is unquestionable.

The main event of the plenary session was a video lecture by Sergey Gaponenko, Academician of the National Academy of Sciences of Belarus, Head of the Laboratory of Nano-Optics at the Stepanov Institute of Physics, entitled "Colloidal Optoelectronics as an Emerging Technology Platform".

As Ivan Kovsh explained before the lecture, colloidal optoelectronics is a new and very interesting field, which is now actively promoted in Belarus.

In his turn, Sergey Gaponenko noted that it is a nascent area which is gradually moving from science to technology and industrial production.

The scientist described in detail the essence of this phenomenon and gave specific examples. He immediately pointed out that the main element of colloidal optoelectronics is the semiconductor crystal. Nanocrystals, he said, occupy an intermediate position between small-atom clusters and massive bulk solids. A nanocrystal retains the features of a crystal, but has one very characteristic feature: it is a quantum 'box' for electrons, which is why nanocrystals have come to be called quantum dots.

Colloidal technology could provide a serious alternative to today's dominant epitaxial technologies in some applications, the scientist is convinced.
