【摘要】:制備雙金屬電極的綠光微腔器件,其結(jié)構(gòu)為Al(15nm)/MoO_3(4nm)/2T-NATA(10nm)/NPB(15nm)/NPB:C545T(x%,20nm)/Alq3:C545T(4%,20nm)/Bphen(35nm)/LiF(1nm)/Al(200nm),其中x為摻雜濃度。實驗表明:當(dāng)摻雜濃度為3%時,器件有最好的光電性能,記為器件B_1。為分析微腔效應(yīng),制備基于ITO的參考器件B_2。B_1和B_2色坐標(biāo)分別為(0.289,0.620)和(0.317,0.557),所以微腔器件的發(fā)光顏色更綠。在100mA/cm~2時,器件B_1和B_2的亮度分別為5076cd/m~2和4818cd/m~2,且最大亮度為9277.7cd/m~2,10440cd/m~2;在100mA/cm~2時,器件B_1和B_2的發(fā)光效率為6.0cd/A和5.61cd/A,且最大發(fā)光效率分別為8.6cd/A和7.97cd/A。與參考器件相比,綠光微腔器件具有更好的發(fā)光效率和顏色純度,其主要歸因于微腔效應(yīng)。
[Abstract]:Preparation of double metal electrode green microcavity device, the structure of Al (15nm) /MoO_3 (4nm) /2T-NATA (10nm) /NPB (15nm) /NPB:C545T (x%, 20nm) /Alq3:C545T (4%, 20nm) /Bphen (35nM) /LiF (1nm) /Al (200nm), where x is the doping concentration. The results show that: when the doping concentration was 3%, the best performance of photoelectric devices, as B_1. device analysis of micro cavity effect, preparation of the reference device B_2.B_1 and B_2 color coordinates based on ITO respectively (0.289,0.620) and (0.317,0.557), so the light color microcavity device more green. At 100mA/cm~2, B_1 and luminance of the device B_2 were 5076cd/m~2 and 4818cd/m~2, and the maximum brightness is 9277.7cd/m~210440cd/m~2; in 100mA/cm~2, B_1 and B_2, the luminous efficiency of the device is 6.0cd/A and 5.61cd/A, and the maximum luminous efficiency is 8.6cd/A and 7.97cd/A. respectively compared with the reference device, green light microcavity device with luminous efficiency and color purity better, It is mainly attributed to the microcavity effect.
