摘　　要：研究了w(TiOPc)=85%、90%、95%时TiOPc/TiO2/AZO三元复合体系的光电导性。研究发现TiO2掺杂对有机光导材料有增感作用。在以TiOPc为主的有机光导材料中掺杂适量的TiO2可以改善光导体的光电导性。在TiOPc/TiO2/AZO三元复合体系中,当m(TiOPc)∶m(TiO2)∶m(AZO)=90∶4∶6时,三元复合体系的光电导性最好,Vr=16V,Rd=14V/s,E1/2=0.64 lx.s。The photoconductivity of TiOPc/TiO2/AZO ternary compound system was studied in this thesis. It was found that titanium dioxide had a sensitization to organic photoconductor. When adulterating a little titani- um dioxide into the system of organic phtoconductor which was made up of primarily by TiOPc,the photocon- ductivity of the system can be improved. When the mass ratio was rn（TiOPc） ： rn（TiO2） ： m（AZO）=90： 4 ： 6, the organic photoconductor shows excellent photoconductivity, and Vr,Rd and E1/2 values are 16V, 4V/s and 0.64lx· s respectively.
