运用新型溶胶凝胶法制备了高比表面积介孔AlPO4玻璃，并通过浸渍法将香豆素102染料镶嵌入该玻璃中。利用激发光谱和荧光光谱方法研究了香豆素102染料镶嵌浓度对光学性质和染料分子的形态的影响。激发光谱结果表明，香豆素102单体分子在介孔AlPO4玻璃中的激发带主要在366 nm处。随着染料摩尔分数从5×10-6 mol/L增加到5×10-3 mol/L，激发峰分裂并逐渐增宽，说明染料分子在介孔玻璃中逐渐聚集成J-二聚体。荧光光谱结果显示，随着染料摩尔分数从5×10-6 mol/L增加到5×10-3 mol/L，主要荧光峰从459 nm红移到479 nm。在浓度5×10-3 mol/L时，可调谐宽度达135 nm。浸析实验证明染料在介孔AlPO4玻璃中稳定性很好。

Mesoporous AlPO4 glass with high surface area is prepared with new sol-gel processing, followed by incorporating coumarin 102 with dipping method. The effects of coumarin 102 concentration on the optical properties of AlPO4 glass and molecular formation of coumarin 102 are studied by excitation spectra and emission spectra methods. The main excitation band placed at 366 nm is ascribed to monomeric coumarin 102 in excitation spectra, and the main excitation band is broadened due to the aggregating of fluorescent dimers in the mesoporous glass as coumarin 102 concentration increases from 5×10-6 mol/L to 5×10-3 mol/L. Red shift of emission band from 459 nm to 479 nm is observed in emission spectra as coumarin 102 concentration increases from 5×10-6 mol/L to 5×10-3 mol/L. The tunable width is 135 nm when the concentration is 5×10-3 mol/L. The stability of the coumarin 102 absorbed in the AlPO4 mesoporous glass is investigated by bleaching experiment.
