Chinese Abstract

本研究中我們將探討六種含不同官能基分子之紅、綠磷光材料(客體),將其各別摻混於三種不同的高分子主體(PVK、UV、PF)中,製作成高效率有機高分子磷光二極體元件,並研究其光電特性。   其內容分成兩部份。第一部份為將三種紅色磷光(R01、R71、R72)材料各別摻混於三種不同高分子基材之主體中,製作成不同變數之元件,探討隨著不同摻混濃度及不同主、客體間的搭配對於元件效率之影響。從實驗中我們發現,當摻混3 wt.%之R71至主體PF中,可得到最佳效率,其最大亮度為3450 cd/m2、最高量子效率值為0.50 cd/A。   第二部份則是使用三種不同綠色磷光(Ir(DBQ)2(acac)、Ir(PPY)2(acac)、Ir(Bzq)2(acac))材料摻混至不同主體中,而以PVK:PBD(1:0.4)摻混5 wt.%之Ir(DBQ)2(acac),其效率最佳,最大亮度達1,3800 cd/m2、最高量子效率值為9.51 cd/A。

English Abstract

In this study, we investigated the photoelectric properties of polymer phosphorescence light emitting diodes, which are made of three different polymers(PVK、UV、PF ) as hosts doped respectively six phosphorescence materials with different functional group molecules. Thus, these PLEDs with high luminance and high quantum efficiency are measured and reported.   The research included two parts, red phosphorescence doping and green phosphorescence doping. In the first part, the result of the three host polymers doped with three red dopants respectively with different process parameters were reported. The highest quantum efficiency and luminance are 0.50 cd/A and 3450 cd/m2 respectiving as PLEDs of PF doped with 3 wt.% R71 radiate.   The Second part is the study of using the same host polymers doped with three different green dopant ((Ir(DBQ)2(acac)、Ir (PPY)2(acac)、Ir(Bzq)2(acac)) to make high efficiency PLED. The highest green quantum efficiency and luminance is up to 0.50 cd/A and 3450 cd/m2 which PLEDs of PVK:PBD(1:0.4) doped with 5 wt.% Ir(DBQ)2(acac) emit.
