Abstract
Organic light-emitting diodes (OLEDs) using tris-(8-hydroxy-quinolinato) aluminum (Alq3) as an emitter, 8-hydroxy-quinolinato lithium (Liq) as an electron injection layer, were prepared. Experimental results show that the efficiency of device with Liq is three times higher than that without Liq. The device using Liq as an injection layer is less sensitive in efficiency to the Liq thickness than that using LiF. In addition to the Alq3 based devices, Liq is also very effective as an electron injection layer for 4,4â²-bis(2,2-diphenylvinyl)-1,1â²-biphenyl based blue OLED and poly (2-methoxy,5-(2â²-ethyl-hexyloxy)-1,4-phenylenevinylene) based orange polymer OLED.
