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。The transparent neodymium-doped phosphate glass-ceramic was prepared by the method of melting and crystallization.The obtained glas-ceramic was characterized by DTA,XRD,SEM,UV-Vis-NIR and fluorescence spectrometry.The results indicate that the main crystal phase of the transparent glass-ceramic is Al2SiO5.The temperature of nuclear generation is in a range from 490540 ℃,and the time of treatment is about 12 h.The temperature of crystallization is at 550 ℃,and the time of treatment is about 13 h.The average grain size is 90 nm.The transparency of the glass-ceramic can reach to 69%,which decreases with the incerease of the heat-treatment time.Because of the concentration increase of Nd^3＋ in the crystal phase after the heat treatment,the peak of the glass-ceramic is stronger than the host glass at 1 056 nm in fluore-scence spectra.
