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,这为新型复合光限幅材料的制备提供了理论基础。Doping Alminum-phthalocyanine-chloride （A1PcCI） into silica gel glass matrix to produce homogeneously doped composites by Sol-gel technique. Study on the composition and structure of the A1PcC1 composite gel glass using transmission electron microscope, scanning electron microscope . And analysis of doping concentration on the UV Vis absorption spectra of influence. By the open aperture Z- scan test and the excited state absorption spectrum test amplitude effect and mechanism of composite xerogels optical limiting are explored. Composite gel glass uniformly doped A1PcC1 are better than that of A1PcC1 in DMF solution for optical limiting effect o The main mechanism for the nonlinear scattering,This is a new type of optical limiting composites preparation provides theoretical basis.
