Vanadyl phthalocyanine ( vopc ) films prepared by vacuum deposition were annealed under magnetic field . uv - visible absorption results showed that the films annealed under magnetic field showed a q - band red - shift . x - ray diffraction study ( xpj ) ) indicated enhancement in diffraction intensity and shift of peak position 分析表明酞菁氧钒分子uv - vis吸收谱q带峰值发生较大的红移； xrd测试中衍射峰强度明显增强，峰位变化，但峰宽变化不大；原子力显微镜( afm )分析发现晶粒大小无明显变化。
