摘要

Abstract

Crystalline white organic light-emitting diodes (C-WOLEDs) are promising candidates for lighting and display applications. It is urgently necessary

however

to develop energy-saving and high-efficiency C-WOLEDs that have stable and powerful emission to meet commercial demands. Here

we report a crystalline host matrix (CHM) with embedded nanoaggregates (NA) structure for developing high-performance C-WOLEDs by employing a thermally activated delayed fluorescence (TADF) material and orange phosphorescent dopants (Phos.-D). The CHM-TADFNA-D WOLED exhibit a remarkable EQE of 12.8%

which is the highest performance WOLEDs based on crystalline materials. The device has a quick formation of excitons and a well-designed energy transfer process

and possesses a fast ramping of luminance and current density. Compared to recently reported high-performance WOLEDs based on amorphous material route

the C-WOLED achieves a low series-resistance Joule-heat loss ratio and an enhanced photon output

demonstrating its significant potential in developing the next-generation WOLEDs.

We report a crystalline host matrix with engineered nanoaggregate structure for fabricating high-performance crystalline white OLEDs (C-WOLED)

showing its significant potential in developing the next-generation OLED technology.
