摘要 研究了光致聚合物的光化学反应理论模型及其动力学参量。合成了染料藻红B和亚甲基蓝作为联合光敏剂共同敏化的全息光存储光致聚合物材料。对材料测试分别得到在曝光波长为633 nm与曝光强度为65 mW/cm2时,透射率随曝光条件的变化关系以及材料各光化学参量。结果表明,随着曝光波长与曝光强度的增加,光致聚合物的光化漂白速率常数k与量子产率Φ增大,当曝光强度为65 mW/cm2时透射率在短波长下出现了下降,光化漂白速率常数k出现负值,而摩尔吸收系数ε在条件不同时则表现了不同的变化趋势。 The photochemical theoretical model and dynamic parameters of the photopolymer are studied. A new holographic photopolymer sensitized by methylene blue (MB) and erythrosine B (ErB) is prepared . This material is tested to obtain transmissivity versus exposure condition and the photochemical parameters with the fixed exposure wavelength of 633nm and intensity of 65 mW/cm^2. Experimental results show that photobleaching coefficient k and quantum yield Ф of photopolymer increase with the exposure wavelength and increase of light intensity. At the intensity of 65 mW/cm^2 transmissivity drops under short wave, photobleaching coefficient k is negative, but the molar-absorption coefficient e shows different changes in different conditions.
