A team from Chairs 67 and 81 and LNBE of MEPhI and Frumkin Institute of Physical Chemistry and Electrochemistry (Russian Academy of Sciences) applied for a patent on the method for making organic light-emitting diodes containing semiconductor nanocrystals

Researchers from Chairs 67 (Condensed Matter Physics), Chair 81 (Physics of Micro- and Nanosystems), and LNBE has applied for a patent on A Hybrid Light-Emitting Diode Structure Based on Organic Semiconductors and Semiconductor Nanoparticles.

Light-emitting diodes based on organic semiconductors, also referred to as organic light-emitting diodes (OLEDs), is the subject of developments in many laboratories all over the world. OLEDs are mainly considered for the use in a new generation of electronic displays that could become an alternative to LCDs and PDPs.

The use of fluorescent semiconductor nanocrystals or "quantum dots" (QDs) as components of the active emission layer substantially increases the efficiency and brightness of OLEDs. The development of such multilayered light-emitting diodes, in particular, the selection of layers of materials with the optimal ratio of energy levels, as well as selection of organic surface ligands of QDs ensuring the optimal parameters of charge transfer in the nanostructures, has been one of the main lines of research and developments in MEPhI and Frumkin Institute of Physical Chemistry and Electrochemistry in recent years.

This work has received well-deserved support from the Federal Research and Development Target Program of the Ministry of Education and Science of the Russian Federation (https://xpir.ru/conference2015/theses/14.575.21.0002).

The designing of the useful model, which we hope to be patented soon, will be an important step towards practical implementation of these developments.
