Abstract

We investigated the effect of quinolate metal complex layer as an electron injection layer on the performance of OLEDs and optimized the device efficiency by varying from 0.5 to 10nm thickness of Liq layer. OLED with a structure of indium tin oxide/$\alpha$-napthylphenylbiphenyl(NPB,40nm)/tris-(8-hydroxyquinoline)aluminum(Alq3, 50nm)/Aluminum(150nm) were fabricated in sequence. The device with 1nm Quinolate metal complex layer showed significant enhancement of the device performance.
