Photoluminescence of one kind of silica was made by a kind of sol-gel method was investigated. The heat treatment temperature of the obtained gel was 5090°C for 2 days and 90°C for 2 hours. Photoluminescence spectra and excitation spectra was investigated and analysed by a Gauss decomposition method. The emission spectra of silica composed of peaks 2.34eV, 2.65 eV and 3.10 eV. The excitation spectrum consisted of 3.1 eV and 5.18 eV. Meanwhile emission of 2.65 eV and 2.34 eV had common excitation peak of 5.18 eV.
