A high-efficiency single-emission-layer (EML) hybrid white organic light emitting device is fabricated based on an ideal sky-blue fluorophor, DADBT, using a novel doping concentration regulation strategy, which effectively separates and respectively utilizes the singlet and triplet excitons in the single-EML. The white device shows excellent electroluminescence performance with maximum total efficiencies of 26.6%, 53.5 cd A(-1) and 67.2 lm W(-1) .
基于理想的天蓝光荧光体 DADBT，采用新颖的掺杂浓度调节策略，制备了高效率的单层发射层（EML）混合白色有机发光器件，有效分离和分别利用了单个 EML 中的单重态激子和三重态激子。该白色器件表现出优异的电致发光性能，最大总效率为 26.6%、53.5 cd A(-1) 和 67.2 lm W(-1)。
