Abstract: Under different annealing temperature, Sm3+-doped SiO2gel and glass were prepared by sol-gel method and three-dimensional fluorescence spectra, excitation spectra and emission spectra of Sm3+in SiO2glass were measured. The results showed that the optimum excitation wavelength is 360nm, the strongest emission wavelength is 610nm, the excitation peak position are at 364, 393, 464nm, the emission peak position are at 578, 591, 595, 610, 732nm, which caused from, respectively,4G5/2—6H5/2,4G5/2—6H7/2,4G5/2—6H11/2transition of Sm3+. The effect of the Sm3+concentration on the emission intensity has been discussed, and the emission intensity of Sm3+became the stronger with increasing the doping concentration. The concentration quenching will occur when concentration of Sm3+exceeds 1.15%.
