P-164: Energy Transfer from Interface Exciplexes to Ultrathin Emissive Layers: A Path Way to Design Simplified Efficient White Tandem Organic Light-Emitting Diodes for Application

Herein, we show a kind of novel tandem white OLED (WOLED) with interface exciplex, which obtaining a high current efficiency of 40.53 cd/A (EQE=18.15%) without light out-coupling technology. The WOLEDs generally show simpler device structure and lower working voltage. Moreover, the designed WOELDs generally emit warm white spectrum with low correlative color temperature of 3701K~4699K. © 2018, Blackwell Publishing Ltd. All rights reserved.
