Tuning the emission characteristics of top-emitting organic light-emitting devices by means of a dielectric capping layer: An experimental and theoretical study
Abstract
The emission characteristics of top-emitting light-emitting devices (OLED) were studied to investigate the effect of a dielectric capping layer. With the capping-layer concept, the outcoupled light intensity in forward direction was increased by a factor of 1.7. The emission characteristics were calculated using an optical model.
