Abstract

A numerical model of multilayer organic light-emitting devices (OLED) is presented in this paper which was consisted of electrical and optical model. The electrical model is based on the drift-diffusion equations. Multilayer organic heterojunctions were mostly considered in this work. A simulation course was programmed with MATLAB. The I-V characteristics obtained show a good agreement with experiment data. The optical model utilizes the optical interface effect, the EL spectrum was calculated with Alq₃ thickness of 40 nm, 50 nm and 60 nm, respectively. The Brightness- Voltage characteristics was simulated, the results and experimental data in the literature are in good agreement on the magnitude.
