摘要:
以4,4’,4″-三(N-3-甲基苯基-N-苯基氨基)三苯胺(m-MTDATA)为空穴注入层,N,N’-二-(1-萘基)-N,N’-二苯基-1,1’-联苯-4,4’-二胺(NPB)为空穴传输层,4-二氰甲烯基-2-叔丁基-6-(1,1,7,7-四甲基久洛尼定-4-乙烯基)-4H-吡喃(DCJTB)为掺杂小分子染料,三(8-羟基喹啉)铝(Alq3)为电子传输层,采用经紫外臭氧氧化处理的银作为阳极,LiF/Al/Ag为超薄复合阴极制备微腔顶发射红光器件.通过光学模拟,研究光输出耦合层对器件发光光谱的影响.结果表明:当采用60 nm的Alq3为光输出耦合层时,在不牺牲器件效率的前提下,器件的光谱角度特性得到极大的改善.
Abstract:
The red top-emitting organic light-emitting device was fabricated by employing the 4,4’,4″-tris(3-methyl-phenylphenylamino)-tri-phenylamine(m-MTDATA)as hole injection layer, N,N’-diphenyl-N,N’-bis(1-naphthyl)-(1,1’-biphenyl)-4,4’-diamine(NPB)as hole transporting layer, 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran(DCJTB)as doping emitting layer, tris(8-hydroxyquinoline)(ALq3)as electronic transporting layer, UV-ozone surface modified Ag as anode and LiF/Al/Ag thin film as cathode, respectively. The effect of out-coupling layer on the emission properties of the TEOLED is discussed in detail through optical simulation. The results illustrate that the spectrum characteristics are improved obviously without sacrificing the efficiency by employing 60 nm thick Alq3 as out-coupling layer.
