以Si、Er、Sn3种分子前驱体为原料，采用溶胶-凝胶法制备了掺Er的锡硅酸盐微晶玻璃复合材料。光学光谱和电子显微镜显示，所得到的材料由包裹亚微米级SnO2晶团的无定形二氧化硅网络组成。发光性能分析表明，Er离子至少部分被捕获在晶相中。拉曼光谱表明，纳米结构的锡-硅酸盐复合材料是稀土离子的低声子能量宿主，因此适合于光子应用。
Er-doped tin–silicate glass–ceramic composites were synthesized from Si, Er and Sn molecular precursors by following a sol–gel method. Optical spectroscopy and electron microscopy showed that the resulting material is composed of an amorphous silica network that encloses submicrometric SnO2 crystalline clusters. Analysis of the luminescence properties shows that Er ions are, at least partially, trapped in the crystalline phase. Raman spectra show that nanostructured tin–silicate composites act as low phonon energy hosts for rare earth ions and are thus suitable for photonic applications.
