| 摘 要： | 利用熔融和晶化技术制备掺钕磷酸盐玻璃陶瓷。 采用差热分析、X射线衍射、扫描电子显微镜、紫外 可见 近红外分光光度计及荧光光谱仪对材料进行表征和分析。 结果表明，在490～540 ℃核化1～2 h，在550 ℃晶化1～3 h，可制得主晶相为Al2SiO5的透明玻璃陶瓷。 其透过率可达69%，晶粒平均尺寸为90 nm，并随热处理时间的增加逐渐增大，但透过率降低。 由于Nd3+在热处理后进入到Al2SiO5晶相中，使荧光谱线在1 056 nm处峰值比原始玻璃强度大。

| Abstract: | The transparency phosphate glass-ceramics which is doped neodymium is prepared by melting and the technology of crystallization. And it is characterized by DTA，XRD，SEM，fluorescence spectrometer. It indicates that the transparent glass-ceramics whose main crystal phase is Al2SiO5 would be made.The temperature of nuclear generation is at the range from 490℃ to 540 ℃,and the time of treatment is about 1h~2h.Then the temperature of crystallization is at 550℃, and the time of treatment is about 1h~3h..The range of grain size is 90nm.Because of the concentrating of Nd3+ in the crystal phase after the heat treatment,the intensity of the peak which belongs the sample is bigger than the intensity which belongs the host glass at 1056nm in fluorescence spectra. |
