在硝酸铽溶液中浸泡和热处理后，观察到了中孔AlPO 4玻璃中铽原子的室温光致发光，其光谱带对应于电子跃迁5D4 → 7 Fj（j = 3-6）。XPS谱表明Tb离子对AlPO 4网络结构的修饰作用。通过Tb掺杂浓度和激发波长的影响，讨论了纳米复合材料的发光机理。研究结果表明，AlPO 4介孔玻璃是一种适合稀土离子掺杂的发光材料。
Intense room-temperature terbium photoluminescence, with well-resolved optical bands corresponding to electron transitions5D4→7Fj(j = 3–6) was observed from mesoporous AlPO4glass after immersion in solutions of terbium nitrates and subsequent heat treatment. The modification of Tb ions for the AlPO4network structure is revealed by XPS spectra. The PL mechanism of the formed nanocomposite is discussed through the effects of Tb concentration and excitation wavelength. Our results indicate that the mesoporous AlPO4glass is a suitable matrix to incorporate rare earth ions as the light emitting material.
