Abstract	가시부 영역에서 산화아연을 광증감시키기 위해 copper phthalocyanine(CuPc)과 sunfast yellow(SY)를 산화아연 분말에 이층 흡착시켰다. 산화아연에 대한 CuPc의 흡착상태를 알기 위하여 ZnO/CuPc의 광음향, IR 및 라만 스펙트럼을 측정한 결과, CuPc는 α형 및 β형의 결정 특성을 유지한 이합체 또는 분자들의 집합체 상태로 산화아연에 흡착된다는 것을 알았다. 산화아연에 CuPc 및 SY를 순차적으로 이층 흡착시킨계(ZnO/CuPc/SY)는 SY를 먼저 흡착시킨 ZnO/SY/CuPc계보다 광기전력이 높게 나타났고, ZnO/β-CuPc/SY는 ZnO/α-CuPc/SY보다 광기전력이 높게 나타났다. ZnO/β-CuPc/SY의 전자사진 감도를 측정하였더니 630 nm에서 S1/2 = 2.99 × 10-2 (erg/cm2)-1 이었다. 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.
