摘要

摘要研究了CuPC(酞菁铜)/ TPD (N,N′-二苯基-N,N′-二(间甲基苯基)-联苯胺)/ PBD(2-(4-联苯基)-5(4-叔丁基苯基)-1,3,4-恶二唑)的电致发光(EL)器件的发射光谱。EL器件发出的蓝光有两个发射最大值，其中一个距离光致发光最大值约50 nm的深色偏移[2]。这种色移是在高电场作用下产生的新能态引起的[1]。

The Optical Characteristics of the Light Emitting Device with TPD and PBD Thin Films

Abstract The emission spectra generated from the electroluminescence (EL) devices on CuPC (copper phthalocyanine) / TPD (N,N′-diphenyl-N,N′-di(m-tolyl)-benzidine) / PBD (2-(4-biphenylyl)-5(4-tert-butyl-phenyl)-1,3,4-oxadiazole) had been studied. The EL devices emitted blue light two emission maxima, and one of them is about 50 nm bathochromic shifted from the photoluminescence maximum [2]. The bathochromic shift is caused by the new energy state generated under a high electric field [1].
