摘　　要：采用 Sol-gel 法将两种具有较高荧光量子产率的四磺化酞菁锌(ZnTSPc)、酞菁氯镓(GaPcCl)分别植入二氧化硅凝胶基质,制备均匀掺杂的复合凝胶玻璃,并对其荧光效应和光限幅性能进行测试。从荧光发射的角度佐证了无机基金属酞菁复合材料的光限幅效应是基于酞菁分子的反饱和吸收机理。Two kinds of fluorescent phthalocyanine, zinc tetrasulfophthalocyanine （ZnTSPc） and gallium phthalocyanine chloride （GaPcCl）, were doped respectively into silica gel glass matrix by sol-gel technique. Homogeneous and transparent composites were produced and their fluorescent spectra and optical limiting behavior were examined. The optical limiting mechanism of resaturable absorption is proved from the fluorescent emission.
