Abstract

|
|
|
For dye sensitization of zinc oxide in the visible region, copper phthalocyanine(CuPc) and sunfast yellow(SY) were adsorbed in two layers on zinc oxide powder. The adsorption structures of α-and β-CuPc on zinc oxide were investigated by photoacoustic, IR and Raman spectra. The α-and β-polymorphs exhibited dimeric structure or molecular aggregates. The surface photovoltaic effect of ZnO/CuPc/SY showed higher than that of ZnO/SY/CuPc and ZnO/β-CuPc/SY indicated better photosensitive than ZnO/α-CuPc/SY. Electrophotographic sensitivity of ZnO/β-CuPc/SY was S1/2 = 2.99 × 10-2 (erg/cm2)-1 at 630 nm.
