摘要

通过高温熔融法和后续热处理制得Tb

掺杂含SrF

纳米晶的透明硅酸盐微晶玻璃。利用X射线衍射（XRD）、透射电子显微镜（TEM）、紫外可见透过光谱、荧光光谱、荧光寿命和X射线激发发光光谱（XEL）探讨了基础玻璃和微晶玻璃的结构和光谱特性。XRD结果表明，玻璃中析出晶体为SrF

纳米晶，衍射峰随着热处理温度的升高和时间的延长而逐渐明显，晶粒也随热处理温度的升高和时间的延长越来越大。在376 nm紫外光和X射线激发下，与基础玻璃相比，微晶玻璃发光显著增强，且发光强度随热处理温度的升高和时间的延长而逐渐增强。

Abstract

doped transparent fluorosilicate glass ceramics containing SrF

nanocrystals were prepared by melt-quenching method with subsequent heat treatment. The structure and luminescence properties of the as-made glass and glass-ceramics were investigated by X-ray diffraction(XRD)

transmission electron microscope(TEM)

transmittance spectra

photoluminescence spectra

fluorescence lifetime and X-ray excited luminescence spectra(XEL). The XRD results show that the precipitated crystalline in the glass matrix is SrF

nanocrystal. The diffraction peaks become obvious and the crystal gradually increases with the increasing of the heat treatment temperature and time. Under 376 nm light and X-ray

much more intense emissions are observed in Tb

doped oxyfluoride glass ceramics containing SrF

nanocrystals compared with the as-made glass. With the increasing of the heat-treatment temperature and time

the emission intensities are enhanced.
