摘要: 本文从X射线光电子能谱和衍射效率两个方面研究了曝光-显影间的间隔时间对重铬酸盐明胶(DCG)全息的影响。结果发现,DCG中的Cr2P3/2的X射线光电子能谱和DCG全息图的衍射效率受曝光-显影间的间隔时间影响较大。DCG中的Cr2P3/2的X射线光电子能谱中的576.4eV附近的峰的相对强度和DCG全息图的衍射效率随这个间隔时间的变化趋势基本相同。即:它们在较长的曝光-显影的时间间隔里,都经历了上升、达到最大值、然后又下降。这些实验结果表明了DCG全息图的衍射率和DCG中的576.4eV附近状态的铬的相对强度的相互依赖性

Abstract: In this paper,the effect of the duration between exposure and development on properties of dichromated gelatin(DCG) holography was studied from two parts of diffraction efficiency and Cr2P3/2XPS(X-ray photoelectron spectrum). It was found that the duration between exposure and development influenced greatly diffraction efficiency and Cr2P3/2XPS. The relative intensity of Cr2P3/2XPS close to 576.4 eV in exposed DCG and the diffraction efficiency of DCG hologram have almost similar change tendancy with duration between exposure and development.Namely,during this duration they all experienced increasing,reaching a maximum,decreasing and finally going to zero. From these experimental results it was indicated that the diffraction efficiency of DCG hologram depends on the relative intensity of Cr2P3/2XPS close to 576.4 eV in exposed DCG.
