Highly Efficient Fluorescent OLED based on TADF Host and Sensitizer

Not Accessible

Your library or personal account may give you access

Abstract

A high EQE of 19.1% using TADF materials as host and sensitizer with a fluorescent emitter TBRb was obtained. The high performance was enabled by utilization of TADF molecules as sensitizer and host that permit efficient transfer of all electrically generated singlet and triplet excitons from the host to sensitizer then to the TBRb.
