ORGANIC LIGHT-EMITTING DIODE FOR INJECTION OF THE CHARGE CARRIERS

摘要

The present invention relates to the field of optics and electroluminescent nanostructures. In particular, the invention relates to light-emitting diodes and applications thereof. An organic light-emitting diode (OLED) comprises a transparent anode (6), a hole transport layer (4) located on the anode (6), an active region located within the hole transport layer comprising semiconductor quantum dots (5), an electron transport layer (3) located at a distance from the active region and a cathode located on the electron transport layer (3), wherein the cathode comprises a layer of 2D-ordered linear-chained carbon (2) and a layer of one of the following materials: a low work function metal and a low work function metal alloy (1).
