摘要：

SiO2:Sm powders prepared by the sol-gel process were structurally characterized by thermogravimetric-differential scanning calorimetry(TG-DSC), Fourier transform infrared(FTIR) spectraoscopy and Si-29 magic angle spinning nuclear magnetic resonance(MAS-NMR). The peaks near 960 cm(-1) in FTIR results are assigned to the deformation vibration of Si-O-Sm linkages, and the samarium ion has been incorporated into the framework of SiO2 as validated by Si-29 MAS-NMR. Blue-green and red photoluminescence(PL) emission in structural disordered SiO2:Sm powders was observed at room temperature with excitation at 380 nm. Study on the luminescence spectra of SiO2:Sm powders with different doping concentrations of Sm3+ indicates that the generation of the special PL hand is related to the formation of Si-O-Sm linkages.
