摘　　要：采用双给体-单受体三元激基复合物体系,制备了单发光层结构黄绿色有机电致发光器件.在该激基复合物体系中,CDBP∶PO-T2T激基复合物的能量有效传递给Ir(ppy)_(3)和Ir(ppy)_(3)∶PO-T2T激基复合物,实现了黄绿光发射.当Ir(ppy)_(3)掺杂质量分数为10%时,器件的EL性能优异.其最大外量子效率、功率效率和电流效率分别为10.5%、21.79 lm/W和31.22 cd/A,发光色坐标为(0.409,0.556),呈现黄绿光发射.此外,该器件在发光亮度为3000 cd/m^(2)时,呈现出约为20%的较低效率滚降.A single-layer yellow-green organic light-emitting diode was fabricated by using a two-donor/one-acceptor ternary excimer system.In this exciplex system,the energy of CDBP∶PO-T2T exciplex is effectively transferred to Ir(ppy)_(3) and Ir(ppy)_(3)∶PO-T2T exciplex,and the yellow-green emission is realized.When the doping concentration of Ir(ppy)_(3) is 10 wt%,the maximum external quantum efficiency,power efficiency and current efficiency of the device are 10.5%,21.79 lm/W and 31.22 cd/A,and the luminescence color coordinates are(0.409,0.556),showing yellow-green light emission.In addition,the device exhibits a low efficiency roll-off of about 20% at a luminance of 3000 cd/m^(2).
