摘要: 自从60年前[1]金属酞菁被发现以来,就引起人们的广泛兴趣,其原因主要在于它们在染料颜料、光化学、催化、和成像中的应用. 和许多其它酞菁衍生物一样,钒氧酞菁具有光导和半导体特性,这使得它在光电子学、电子成像、化学传感器、甚至于微电子器件中有潜在的十分光明的应用前景[2]. 例如, 钒氧酞菁在电子成像体系中已成为有用的感光材料. 近年来,金属酞菁等有机材料的结晶薄膜开始不断地吸引人们的注意力. 人们考察了不同的金属酞菁如: 酞菁铜、酞菁铅、酞菁镍、和酞菁锡 等的光电导和光电压[3]. 通常酞菁以几种不同的多晶异构体、即以不同的晶体排列结构方式存在. 因此,其光电特性不仅取决于分子中心的金属原子、而且取决于它们的晶体结构. 总之,值得我们研究钒氧酞菁薄膜的光电特性以及它与吸收光谱和薄膜晶体结构的关系.

Abstract: In this paper, a modifcation of the procedure reported by Barret was applied to synthesize vanadyl phthalocyanine(VOPc) which gave higher yield and easier to carry out. The purified VOPc was employed to Al\VOPc\ITO sandwich cell by vacuum deposition. Three phases of VOPc films have been discovered and their absorption spectrum, the steady-state cw(continious wavelength) photovoltage response of the cells have been investigated. It has been found that the structure of the VOPc film influences the absorption and photoelectronic properties remarkably. Two of the three phases of VOPc films, phase I and phase Ⅱ gave obvious positive photovoltage response which was abnormal from the α-form film that gave only negative photovoltage response. This abnormal phenomenon could be explained by assuming that the negative and positive photovoltage response might be related to Q-excitation and nonlinear effects respectively.
