Simulation of electroluminescence using a bipolar recombination model

Abstract

A dynamic bipolar charge recombination model originally developed to explain charge injection and electroluminescent (EL) behaviour of pin-plane polymeric resin samples under ac stress has been adapted to allow the simulation of EL from polyethylene films sandwiched in a plane-plane electrode system. The model is described and obtained results compared with experimental measurements. Comparison reveals that there is good agreement between the model and experimental data, indicating that under ac stress and in this case EL may be entirely due to charge injection and bipolar recombination. ©2007 IEEE.
