摘要

研究了2-TNATA 厚度对蓝与黄二基色分离的堆叠式白色有机发光器件性能的影响。器件结构为: 2-TNATA(

nm)/NPB(25 nm)/ADN(30 nm)∶TBPE(2%)∶DCJTB(1%)/Alq

(20 nm)/LiF(1 nm)/Al(100 nm)。根据实验结果

2-TNATA的厚度对载流子的注入、色稳定性、热稳定性影响明显。发光器件的颜色可以通过改变加入的2-TNATA层的厚度来改变。这种器件使用2-TNATA作为空穴注入层显示出了色纯度高的白光发射

Abstract

This paper systematically investigated the effect of the thickness of 2-TNATA on the characteristics of stacked white organic light-emitting devices consisting of separate blue and yellow elements. The device structure was 2-TNATA(

nm)/NPB(25 nm)/AND(30 nm) ∶ TBPE(2%) ∶ DCJTB (1%)/Alq

(20 nm)/LiF(1 nm)/Al(100 nm). According to the experimentation result

it was found the effects of thickness of 2-TNATA on carrier injection

color and thermal stability was very significant. The color of the white device can be adjusted by changing the thickness of 2-TNATA inserted. The device using 20 nm 2-TNATA as a hole injection layer showed pure-white light emitting with 1931 CIE chromaticity coordinates

=0.319 7

=0.349 6

and the luminance of 12 230 cd/m
