Ce 3+ -doped silica was synthesized by sol–gel technique and was further decorated with S 2− and Cl − anions through chemical exchange in controlled ambient at elevated temperature. The structure and optical property of samples were examined by X-ray diffraction spectrum, XPS pattern, reflection pattern, and photoluminescence patterns. There is a broad luminescence band at...
Ce 3+ -doped silica was synthesized by sol–gel technique. The absorption band at 252nm of Ce 3+ -doped silica is close to the main absorption band of Ce(NO 3 ) 3 solution. Three different luminescence bands were observed in the samples annealed at temperatures from 100 to 1200°C, and the intensity of these luminescence bands changed with the alteration of the heat-treating...
