摘　　要：文章讨论了采用真空热蒸镀的方法制备了适用于夜间照明的有机发光器件.器件选用热活化延迟荧光材料DPEPO作为发光层主体材料,热活化延迟荧光材料DMAC-DPS作为蓝光掺杂剂,PO-01作为橙光发射的磷光掺杂剂.器件结构为ITO/TCTA(20 nm)/DPEPO:x%DMAC-DPS:0.6%PO-01(15 nm)/TAZ(20 nm)/LiF(0.8 nm)/Al(100 nm).通过改变DMAC-DPS的掺杂浓度来研究器件性能的变化.实验结果表明:当x=20时,器件的最大电流效率可达26.19 cd/A,最大功率效率可达7.47 lm/W,最大亮度可达4 619 cd/m^2,器件的发光效率较高.In this paper, organic light-emitting devices （OLEDs） for illumination were made by vacuum thermal evaporation. The thermally activated delayed fluorescence material DPEPO was chosen as the host material for the luminescent layer, thermally activated delayed fluorescence material DMAC-DPS as a blue light emitting dopant and PO-01 as a phosphorescent dopant for orange light emission. The structure of device was ITO/TCTA（20 nm）/DPEPO：x% DMAC-DPS：0.6% PO-01 （ 15 nm）/TAZ（20 nm）/LiF（0.8 nm）/Al（ 100 nm）. The device performance was studied by changing the doping extent of DMAC-DPS. The best performance is achieved when x is 20. The maximum current efficiency of the device can achieve 26. 19 cd/A, the maximum power efficiency can achieve 7.47 lm/W and the maximum luminance can achieve 4 619 cd/m2 when x is 20.
