    Microstructure and Photoluminescent Properties of Eu3+:SnO2 Glass Ceramics

      摘要
    • 摘要: 采用溶胶-凝胶法制备了Eu3+:SnO2微晶玻璃, 研究了它的显微结构和光致发光性能。结果表明: 干凝胶在高于400 ℃热处理后可得到含金红石结构SnO2纳米晶的微晶玻璃; 随着热处理温度升高, SnO2的特征峰出现了红移; 在280 nm紫外光激发下, 800 ℃热处理得到的微晶玻璃的发射光谱中出现了Stack分裂, 表明Eu3+进入到SnO2晶体中。

       

      Abstract: 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.
