摘要

采用真空热蒸镀的方法

在常规的双层器件结构的基础上

设计了三层双异质结有机电致发光器件(OLED):indium-tin oxide(ITO)/N

N'-diphenyl-N

N'-bis(1-naphthyl)(1

1'-biphenyl)-4

4'-diamine(NPB)/2

9-dimethyl-4

7-diphenyl-1

10-phenan throline(BCP)/8-hydroxyquinoline aluminum(Alq

)/Mg:Ag。通过对器件的电致发光(EL)光谱及器件性能的表征

研究了不同超薄层BCP的厚度对OLED器件性能的影响。结果表明

当超薄层BCP的厚度从0.1nm逐渐增加到4.0nm时

器件的EL光谱实现了绿光→蓝绿光→蓝光的变化;BCP层有效地调节了载流子的复合区域

改变了器件的发光颜色

提高了器件的亮度和发光效率。
