采用溶胶-凝胶浸涂法制备了掺杂罗丹明 6G (Rh6G) 的 AlPO4-SiO2 薄膜。表面形态通过原子力显微镜进行表征。结果表明，薄膜的表面形貌并未受到染料负载量的显着影响。吸收和激发光谱表明，即使在 Rh6G 掺杂浓度为 1.0 × 10-3 mol/L 时，聚集也较低。观察到以 553 nm 为中心的有效荧光带。
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.
