酞菁氯镓复合凝胶玻璃的谱学性能研究

Study on the Spectral Properties of Gallium-Phthalocyanine-Chloride Doped Composite Gel Glass

采用溶胶-凝胶(Sol-Gel)湿化学工艺将酞菁氯镓(GaPcCl)掺入二氧化硅(SiO2)凝胶玻璃基质,制备出均匀掺杂的GaPcCl复合凝胶玻璃,并对复合体系的红外光谱(IR)、紫外-可见吸收光谱(UV-Vis)及荧光光谱等谱学性能进行了测试。结果表明:GaPcCl的掺杂对凝胶玻璃基质的红外光谱没有产生显著影响;掺杂GaPcCl在复合体系中二聚体吸收峰的强度较其DMF溶液有所增大;掺杂GaPcCl在复合体系中荧光强度随浓度的增加远大于DMF溶液。

One of the focal topics in the field of phthalocyanine research is its materialization for practical use. The present paper reports the encapsulation of gallium phthalocyanine chloride （GaPcC1） into silica gel glass to make homogeneously doped compos ite by sol-gel technique. The spectral properties of the composite gel glass were carried out by IR, UV-Vis and fluorescence measurements. The results show that the introduction of GaPcCl doesn ＇t make noteworthy changes in the IR spectra of silica gel glass matrix. The absorption of GaPcCl dimers increases compared with DMF solution. The fluorescence intensity of GaPcCl is greatly enhanced in the composite gel glass.
