摘要	Herein, highly efficient single-emitting-layer structure pure fluorescent white organic light-emitting diodes (WOLED) were designed by employing thermally activated delayed fluorescence emitter of mSOAD as host material to sensitize traditional fluorescent dopant of Rubrene and DCJTB, respectively. The WOLED based Rubrene dopant achieve a cool white emission with maximum current efficiency, power efficiency and external quantum efficiency of 33.0 cd/A, 34.5 l m/W and 12.2%, respectively. While a warm white emission with the efficiency of 20.9 cd/A, 20.1 lm/W and 9.0%, respectively, were realized in WOLED based DCJTB dopant. The study to energy level and photoluminescence transient decay lifetime demonstrate the sufficient confinement to charges and excitons, and efficient triplet collection by host triplet exciton reverse intersystem crossing and energy transfer to dopant are the reasons of high device efficiency and stable spectra.
