Hybrid light-emitting diode based on organic semiconductors and fluorescent semiconductor nanocrystals invented at Chairs 67 and 81 and LNBE to be defended by a patent from Rospatent

Federal Agency for Intellectual Property (Rospatent) informed on the decision to issue a utility model patent on A Hybrid Light-Emitting Diode Structure Based on Organic Semiconductors and Semiconductor Nanoparticles designed by a research team from Chairs 67 (Condensed Matter Physics) and 81 (Physics of Micro- and Nanosystems) and LNBE.

The novel light-emitting diode is a multilayered structure containing, among other layers, a layer of AIIBIV fluorescent semiconductor nanocrystals (so-called quantum dots) and a composite layer of quantum dots embedded in polyfluorene, an organic semiconductor.

The inclusion of quantum dots and composite materials containing them into the structure of an organic light-emitting diode provides a substantial increase in its efficiency and brightness.

More details on this device were reported at the LNBE website earlier.
