摘要

通过研究新型荧光材料2-(2-溴-5-乙烯-噻吩)-8-羟基喹啉锌(BTHQZn)的电致发光特性

发现BTHQZn具有良好的电致发光特性和空穴传输特性

利用此特性制备了掺杂型有机电致黄光器件

结构为ITO/2T-NATA(30 nm)/CBP ∶ 5%Ir(ppy)

∶ 10%BTHQZn(20 nm)/Alq

(50 nm)/LiF(0.5 nm)/Al

器件在12 V时实现了黄绿光发射

最大发光亮度为4 552 cd/m

色坐标为(0.395 4

0.497 6)

在11 V电压下的最大发光效率为2.82 cd/A。

Abstract

The electroluminescence (EL) characteristics of a novel yellow emitting material (BTHQZn) were investigated in this paper. The results demonstrated the BTHQZn with strong emitting and hole-transporting ability.Based on the performances

a series of un-doping and doping yellow organic light-emitting diodes (OLEDs) were fabricated. The yellow device was fabricated as follows: ITO/2T-NATA(30 nm)/CBP ∶ 5%Ir(ppy)

∶ 10%BTHQZn (20 nm)/Alq

(50 nm)/LiF(0.5 nm)/Al

the maximum luminance was 4 552 cd/m

at an applied voltage of 12 V

while the Commission International de LEclairage coordinates was (0.395 4

0.497 6)

and the maximum luminous efficiency was 2.82 cd/A at applied voltage of 11 V.
