Microstructure and Photoluminescent Properties of Eu3+:SnO2 Glass Ceramics

Eu3+:SnO2 glass ceramics was prepared by sol-gel method, and its microstructure and photoluminescent properties were studied. The results show that the glass ceramics with rutile SnO2 nano-crystals were obtained after dry gel was heat-treated at over 400 ℃. The characteristics peak of SnO2 nano-crystals showed red-shift with the increase of heat treatment temperature. Stack split appeared in the emission spectrum of the glass ceramics obtained at 800 ℃ when it was excited by UV-light with wavelength of 280 nm, this indicated that Eu3+ entered into the SnO2 crystal.
