Yellow Organic Light-Emitting Devices Based on Alq Doped DPIHQZn

Abstract:

The Electroluminescence (EL) characteristics of a novel yellow emitting material (DPIHQZn) were investigated in this paper. The results demonstrated the DPIHQZn with strong emitting and hole-transporting ability. Based on the performance,a series of doping yellow organic light-emitting diodes were fabricated.The yellow devices were fabricated as follows: ITO/ 2T-NATA(40 nm)/NPB(10 nm)/Alq:x%DPIHQZn (35 nm)/Alq (35 nm)/LiF(5 nm)/ Al,x=1,2,3,5;the maximum luminance was 3180 cd/m²at an applied voltage of 15V,while the Commission International de LEclairage coordinates was (0.40,0.48).
