A tunable luminescence from red to blue in Eu-doped mesoporous AlPO4 glass is achieved by adjusting the annealing temperature. With increasing annealing temperature, the increased Eu3+ ions reduction changes the luminescence of the obtained glass. The abnormal reduction of Eu3+ to Eu2+ occurs in AlPO4 mesoporous glass at relative low annealed temperatures from 600 to 800 oC in air. The presence of Eu2+ ions, which are reduced from Eu3+ by hole-electron pairs, is revealed by XPS spectra. Our results indicate the mesoporous AlPO4 glass is a suitable matrix to incorporate Eu ions as the tunable luminescent light sources or LEDs.

AlPO4-SiO2 films doped with Rhodamine 6G (Rh6G) are prepared using the sol-gel dip-coating method. The surface morphology is characterized by atomic force microscopy. The results indicate that the surface morphology of the films is not significantly affected by the amount of dyes loaded. The absorption and excitation spectra indicate low aggregation even at a Rh6G doping concentration of 1.0 \times 10-3 mol/L. Efficient fluorescence with a band centered at 553 nm is observed.

运用新型溶胶凝胶法首先制备介孔AlPO4玻璃，然后通过浸渍法将7-羟基-4三氟甲基香豆素染料（7-香豆素）镶嵌入该玻璃中. 通过激发光谱和荧光光谱研究了7-香豆素染料镶嵌浓度以及AlPO4玻璃介孔孔径对光学性质和染料分子的形态的影响。激发光谱表明，7-香豆素单体分子在介孔AlPO4玻璃中的激发带主要在372 nm处。随着染料浓度从1×10-6 mol/L增加到1×10-2 mol/L，激发峰逐渐蓝移至362 nm处，说明染料分子在介孔玻璃中逐渐聚集成H-二聚体。荧光光谱结果表明，随着染料浓度从1×10-6 mol/L增加到1×10-2 mol/L，其主要荧光峰从421 nm红移到435 nm。通过镶嵌浓度1.0×10-4 mol/L时两种介孔AlPO4玻璃的发射光谱和激发光谱可以表明，孔径为3.52 nm的介孔玻璃的主要发射峰为428 nm，激发峰为370 nm，而孔径为6.74 nm的介孔玻璃发射峰相对红移至433 nm，激发峰蓝移至365 nm，说明较小孔径的介孔AlPO4玻璃抑制染料的聚集效应更好，有利于高浓度染料的镶嵌。

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。

AlPO4 mesoporous glass doped with perylene orange (PO) is prepared using two steps. The effects of dipping time and PO concentration on the fluorescent properties and molecular formation are investigated through absorption spectra, excitation spectra, and emission spectra. A slight increase in the intensity of excitation bands formed at 499 and 468 nm is ascribed to PO J-dimers aggregates as the dipping time increased from 2 to 24 h at high PO concentration (4×10^-3 mol/L). This is also the reason behind the concentration increase from 4×10^-6 to 4×10^-3 mol/L for the 16 h dipping. The excitation spectra, and the emission spectra of samples doped with PO show a slight red shift as the dipping time and the PO concentration increase. AlPO4 mesoporous glass is suitable to host the PO at high concentration.
