氯铝酞菁复合凝胶玻璃的制备及光限幅效应研究

摘要

采用溶胶—凝胶(Sol-gel)工艺在二氧化硅(SiO2)凝胶玻璃基质中掺入氯铝酞菁(AlPcCl)，制备了掺杂 AlPcCl 的复合凝胶玻璃；采用透射电子显微镜、扫描电子显微镜研究了 AlPcCl 复合凝胶玻璃的组成和结构并且分析了掺杂浓度对其紫外-可见吸收光谱的影响；通过开孔 Z-扫描测试和激发态吸收谱测试对复合干凝胶的光限幅效应和机理进行了探索。结果表明均匀掺杂 AlPcCl 的复合凝胶玻璃具有优于 AlPcCl 在 DMF 溶液中的光限幅效应，其主要机理为非线性散射，这为制备性能优异的新型复合光限幅材料提供了理论依据和物质基础。%Doping Alminum - phthalocyanine - chloride (AlPcCl)into silica gel glass matrix to produce homogeneously doped composites by Sol-gel technique.The exciting state and structure of doped AlPcCl was studied by Transmission Electronic Microscope,Scanning Electronic Microscope and UV/Vis absorp-tion spectra.The optical limiting mechanics of AlPcCl in composites was studied by excited absorption spectra,optical limiting and Z-scan experiment.Several important results are obtained.
