| 摘 要： | 文章采用喹啉氮杂环类锒配合物（PPQ）2Ir（acac）]为客体，以聚芴和2-（4-二苯基）-5-（4-叔丁基苯基）-1，3，4-噁二唑（PBD）为主体，研究了不同发光层厚度对有机电致发光器件性能的影响．随着发光层厚度的增加，相同电压下器件的电流密度和发光亮度逐步减小，表现出明显的电荷捕获机制．当厚度达到70nm时，得到了发光亮度为1792cd／m^2，发光效率为6．16cd／A的高性能红光器件．

| Abstract: | The red phosphorescent organic light-emitting devices(OLEDs) with various thickness of emitting layer,employing bis(2,4-diphenylquinolyl-N,C2')iridium(acetylacetonate) (PPQ)2Ir(acac)] as the guest and a blend of poly(9.9-dioctylfluorene)(PFO) with 2-(4-biphenyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole(PBD) as the host have been reported.With the increase of film thickness,the red OLEDs show a decreased current density and luminance under same voltage.This result demonstrates the charge trapping in the gues... |
