MoO3作空穴注入层的绿光有机电致发光器件制备及其性能研究
Fabrication and Performance Research of Green Organic Light Emitting Device with MoO3 Hole Injection Layer
摘要
Abstract
A green organic light emitting device(OLED) with the structure of ITO/MoO3 (x nm)/N,N'-diphenyl-N,N'-bis(l-naphthyl)-(l,18-biphenyl)-4,4-diamine(NPB)(40 nm)/tris (8-hydroxyquinoline)aluminum(Alq3 ) (60 nm)/LiF(l nm)/Al(150 nm) have been fabricated by vacuum deposition method,x = 0,5 nm. The detail process has been described. It was found that the treatment on the surface of ITC) substrates by oxygen plasma can effectively reduce the contact angle of the ITO surface in the experiments. By measuring and analyzing the performance of luminescence and electrical of device, the influences of the hole injection layer MoO3 on device performance was investigated. Experimental results show that HOMO level of MoO3 can reasonably match ITO work function, which reduces the hole-injecting barrierand improves the brightness and efficiency of device. When forward voltage is less than 10 V, the current density of device does not change significantly with the voltage increases; When the voltage is more than 10 V, the current density increases significantly. The chroma of device stabilizes in green light district of(0. 36, 0. 55) with the changes of the driving electric voltage.关键词
