摘　　要：　四苯基卟啉铂(PtTPP)可以作为红光掺杂材料制备有机电致发光器件,采用的器件结构为[ITO/CuPc/NPB/BePP2∶PtTPP/LiF/Al],其中BePP2∶PtTPP的共沉积膜作为发射层.实验结果表明在发射层中存在着从BePP2到PtTPP的能量传递.通过改变掺杂层中PtTPP的浓度来考察器件的性能,当PtTPP的掺杂浓度在8%(物质的量比)时,器件呈现纯正的红光发射,发射峰位于668nm,器件的效率为0 004lm/W.Luminescent tetrakis(phenyl)porphyrin platinum(Ⅱ)(PtTPP) complex was employed as a doped emitting material to fabricate red organic electroluminescent(EL) devices.The EL device structure was [ITO/copper phthalocyanine(Cu-Pc)(15 nm)/(N,N′)-di(α-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine(NPB)(600 nm)/tris(8-hydroxyquinolinato)aluminum(Alq_3)∶PtTPP(50 nm)/LiF(1 nm)/Al(200 nm)].The codeposited films of Alq_3∶PtTPP were utilized as emitting layer to construct EL devices.Experimental results showed that energy transfer from Alq_3 to PtTPP occurred in the codeposited films.The EL property of codeposited Alq_3∶PtTPP films with different PtTPP concentrations were described.For the EL device with PtTPP concentration of 15% by weight,deep red electroluminescence at 656 nm with maximum EL efficiency of 0.004 lm/W was achieved.
