HYBRID QUANTUM DOT/METAL-ORGANIC LED WHITE LIGHT SOURCE

摘要

This invention relates to the field of optics, in particular, to electroluminescent nanostructures, and can be used at creating of efficient lighting devices of distributed light for inner lighting. It is proposed to use a construction of hybrid organic light emitting diode with an active layer based on a metal-organic phosphor doped by quantum dots that provides a source of distributed white light. Specific feature of design is the use of metal-organic phosphor as a blue light source, and the fact that emission of complementary colours is provided by quantum dots (nanoparticles), which are synthesized with possibility to change a diameter of semiconductor core within 2.0-6.0 nm and the thickness of semiconductor shell within 1.0-3.0 nm. An object to be achieved by means of this invention is creation of the white light source based on OLED device with use of one active layer on the basis of quantum dot hybrid material.
