| 摘 要： | 蓝色聚合物发光二极管是人们关注的课题,前不久,我们报道1]了利用ITO/PVCz/BBOT/Mg·Ag结构达到亮度1700cd/m2,量子效率0.2%的蓝色器件.在本文中我们报道以掺杂perylene(PRL)和triphenylamine(TPA)的poly(N-vinylcar-bazole)(PVCz)为空穴传输层,以PBD为空穴锁住层,Alq为电子注入层的器件,其亮度达6100cd/m2,量子效率达0.7500,流明效率0.451m/W的蓝色发光器件.就我们所知,这个亮度是蓝光中最高的亮度.

| Abstract: | Blue emitting dlode using polyvenylcarbazole(PVCz) doped with perylene(PRL)and trlphenylamlne(TPA) as a hole transporting layer,2-(4''-tert-butyphenyl)-5-(4"-biphenyl)-1,3,4-oxadiazole(PBD)as a hole blocking layer and 8-hydroxyquinolinealumlrlum(Alq) as an electron injection layer has been constructed.By the dopingofTPA the performence of the device was impvoved.A luminance as high as 6100cd/m2with quantum efficiency 0.75% has been obtained.Energy diagram of the device was obtained bymeasured HOMO levels and band gaps of the materials used.Based on the energy diagram the balance of electrons and holes for diffirent devices was analyzed and the effect of TPA doping on diffirent devices was discussed. |
