中文摘要：
以MoO3或m-MTDATA作为空穴注入层,Alq3或Bphen作为电子传输层组合了4组白色有机电致发光器件。发光层为9,10-bis(2-naphthyl)-2-t-butylanthracene(TBADN)掺杂3%的P-bis(P-N,N-diphenyl-aminos-tyryl)benzene(DSA-ph)作为蓝色掺杂剂和0.05%的4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7,-tetramethyl-julolidy-9-enyl)-4H-pyran(DCJTB)作为红色掺杂剂。研究表明基于MoO3//Bphen结构的器件大大降低了驱动电压,改善了功率效率,在电流密度为20mA/cm2时,其值分别为5.43V和4.54lm/W。与基于m-MTDA-TA//Alq3结构的器件相比,驱动电压降低了40%,功率效率提高57%。
