摘要

利用旋涂法和真空蒸镀法相结合的方法

根据能量空间传递的原理制备了PVK ∶ Ir(piq)

(acac)体系的红色有机电致发光显示器件。器件的结构为ITO/CuPc/PVK ∶ Ir(piq)

(acac)/BCP/Alq

/LiF/Al。研究了不同主客体掺杂比对器件发光性能的影响

得到了高色纯度、单色性较好的红光器件。当Ir(piq)

(acac)掺杂的质量比为1 ∶ 0.08时

器件的综合性能达到最佳

发光峰位于625 nm

CIE坐标为(

=0.66

=0.33)。通过对各层厚度的合理选择

形成相对优化的微腔结构

充分利用其对光谱的窄化效应

使得器件的EL光谱的发射半峰全宽仅为55 nm

提高了器件的发光性能。器件光谱具有很好的单色性

色纯度达到98.2%。
