Abstract Electrical pumping of organic semiconductor devices involves charge injection, transport, device on/off dynamics, exciton formation and annihilation processes. A comprehensive model analysing those entwined processes together is most helpful in determining the dominating loss pathways. In this paper, we report experimental theoretical results Super Yellow (Poly( p -phenylene vinylene) co-polymer) light emitting diodes operating at high current density under voltage nanosecond...
Phosphorescent organic light emitting diodes (OLEDs) suffer from efficiency roll off, where device rapidly decays at higher luminance. One strategy to minimize this loss of luminance is the use non-uniform or graded guest:host blend ratios within emissive layer. This work applies a multi-scale modeling framework elucidate mechanisms by which ratio can change performance an OLED. Mobility and exciton data are extracted kinetic Monte-Carlo model, then coupled drift diffusion model for fast...
