Efficient doped and non-doped OLEDs based on a deep-blue HLCT material and all-HLCT WOLEDs with standard white-light emission
Source abstract
Abstract
Blue and orange HLCT materials ( CzPyPPI and BTPA4 ) are developed. CzPyPPI enables OLED with deep-blue emission (CIE y =0.063). An all-HLCT WOLED yields near-standard white light with an EQE max of 6.86% and low efficiency roll-off.
