Abstract

The invention discloses an OLED (Organic Light Emitting Diode) device prepared by taking di(8-hydroxyquinoline)platinum as a doped material, taking indium tin oxide (ITO) as transparent conductive film glass (an anode), taking N,N'-di(1-naphthyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine (NPB) as a hole transport material, taking 4,4'-di(9-carbazole)biphenyl (CPB) doped with di(8-hydroxyquinoline)platinum (Ptq2) as a main raw material, taking 2,9-dimethyl-4,7-biphenyl-1,10-phenanthroline (BCP) as a hole blocking material, taking 8-hydroxyquinoline (Alq3) as an electron transport material and taking aluminum / lithium fluoride as a cathode. According to the OLED device prepared by doping Ptq2 which serves as a phosphor material in the main raw material, the maximum electroluminescence wavelength is within a near-infrared area (700-850nm), and the OLED device has excellent electrical conductivity and stability.

Description

technical field

[0001] The invention relates to the technical field of organic electroluminescence, in particular to an OLED device doped with bis(8-hydroxyquinoline) platinum. Background technique

[0002] Organic electroluminescent technology (OLEDs), as one of the internationally recognized new-generation flat panel display technologies, has active light emission compared with the main flat panel display products on the market such as liquid crystal displays; the manufacturing process is simple, the cost is low; and the power consumption is low; Large viewing angle; light weight, small size; fast response, etc. Compared with fluorescent light-emitting materials, phosphorescent materials can effectively utilize singlet and triplet excitons, and can obtain a larger external quantum yield. Organic phosphorescent materials are being used in electroluminescent devices due to their high electroluminescence efficiency.

[0003] At present, there are few systematic studies on n...
