摘要：
A model for carriers injection, transport and recombination in single layer organic light emitting diodes was presented. The electric field contribution, the relationship between current density and the applied voltage,and the recombination efficiency were obtained by solving the nonlinear Painleve equation. When the majority of carriers had lower mobility, the carriers were easy to get injection and transport, and the device efficiency could be improved. If the hole mobility was larger than the electron mobility, the recombination zone moved towards cathode, and vice versa.
