摘要 OLED是一种主动发光器件 ,影响器件发光性能的因素很多 ,如电子流与空穴流间的平衡、发光层内电子与空穴的有效复合、外部注入非平衡载流子的能力等。外部注入非平衡载流子的能力与金属 -半导体的界面特性有关。本文基于热电子发射理论论述了电极用金属的功函数与非平衡载流子注入的关系 ,说明其对 OLED is a kind of actively light emitting device.Many factors can influence its light emitting performance,such as the balance of electron and hole currents,the efficient capture of holes and electrons in the emissive layer and the efficiency of externally injected unbalanced charges,and so on. The efficiency of externally injected unbalanced charges is related to the interface characteristics of metal semiconductor. Based on heat electron emission theory, the relationships between workfunction of metal for electrode and externally injected unbalanced charges are obtained here. And we explain the influence of workfunction of metal for electrode on OLED light emitting performance.
