Polymeric organic light emitting diodes (OLED)

Abstract

The construction and performance of a series of polymeric guest-host type OLEDs is described. We examine the I-V-L properties of OLED as a function of the device configuration (film thickness, 1-layer vs multi-layer devices, etc.) and of its constituents (composition, use of additives, etc.). Data analysis on the various charge transport regions also shed light onto the overall transport mechanism and critical performance criterion.
