摘要

设计并制作了两个器件

一个是微腔有机电致发光器件(MOLED):G/DBR/ITO/NPB(46 nm)/DPVBi(20 nm)/Alq

(56 nm)/LiF(1 nm)/Al(150 nm);一个是无腔器件(OLED):G/ITO/NPB(46 nm)/DPVBi(20 nm)/Alq

(56 nm)/LiF(1 nm)/Al(150 nm)。测试并分析了器件性能。OLED在电流密度30 mA/cm

时的电致发光(EL)光谱随观测角度由0°~70°都是一宽谱带

是发光层DPVBi的特征发光谱

峰值都在452 nm处

半峰全宽均为70 nm

色坐标均为

(x=0.18

y=0.19)

无腔器件没有角度依赖性。相同电流密度下

微腔器件的EL谱随观测角度由0°~70°

发光峰值蓝移

由472 nm逐渐移至428 nm;峰值相对强度渐弱

由0.32变至0.02;半峰全宽由14 nm增加至120 nm;色坐标由(

=0.14

=0.10)变至(

=0.19

=0.25)

颜色由紫蓝变成蓝白到接近白色。微腔器件具有明显的角度依赖性。
