【摘要】 建立了载流子在单层有机发光二极管中注入、传输和复合的理论模型,通过求解非线性Painleve方程得出了电场强度随坐标变化的解析函数关系式以及电流密度随电压变化关系(即J-V 关系)。场强分布及J-V 关系受载流子迁移率影响较大,在器件中占主导地位的载流子应具有较低的迁移率,这样有利于载流子的注入和传输,发光效率可相应得到提高。更多还原

【Abstract】 A model for carriers injection, transport and recombination in single layer organic ligh emitting diodes hasbeen presented. By solving the nonlinear painleve equation, we have been achieved the electric field contribution andthe J-V relationship. We find that the carriers mobilities have high effects on them. When the majority carrier has thelower mobility, the carriers are easy to injection, transport, and the device efficiency has been improved.更多还原
