摘要: 采用熔融和晶化技术合成出含CaF2微晶的Nd3+离子掺杂透明氟氧化物玻璃陶瓷材料, 并通过DTA, XRD, FEG-ESEM和UV-Vis-Nir分光光度计和傅里叶变换荧光光谱仪等对样品进行了表征. 结果表明, 玻璃陶瓷主晶相为CaF2, 晶相粒径为15 nm; 可见光透过率为78%~87%, 近红外透过率为84%~93%; 由于Nd3+在热处理后优先富集在具有低声子能量的CaF2晶相中, 从而改变了配体场, 使荧光谱线在1060 nm处的峰值比原始玻璃强度大.

Abstract: Nd3+-doped transparent oxyfluoride glass ceramics containing CaF2 was prepared through controlled crystallization of melt-quenched glass. The sample is characterized by DTA, XRD and FEG-ESEM. The result indicates that the main phase of crystal is CaF2 and the crystalline particle size is 15 nm. The optical transmittance is about 78%—87% in the visible region and 84%—93% in the near-infrared region. Fluorescence measurements exhibit a stronger emission especially at 1060 nm in the glass ceramics than in the precursor glass, and a larger excited emission section value than the precursor glass, due to the incorporation of Nd3+ into CaF2 during the crystallization.
