摘要: A phosphorescent blue organic light-emitting diode device disclosed by the present invention comprises a first conductive layer, hole transport part, an electronic transmission part and second layer which are deposited orderly. The is formed doping at least one delay fluorescent material material, concentration of in 50wt.%-99wt.%, 1 wt.%-50wt.%. emission spectrum absorption overlapped partially, singlet state energy level set as S1, triplet T1, difference delta E (S1-T1) less than 1.0eV. provided enables exciton utilization rate to be improved return characteristic, thereby improving efficiency.
