【摘要】 采用熔融及分部晶化法制备出掺钕 SiO₂-Al₂O₃-P₂O₅系微晶玻璃．采用差热分析、X 射线衍射及荧光光谱仪对材料进行表征．结果表明,在490～ 590℃保温2～4h,而后在600～700℃保温5～7h,可制得主晶相为 AlPO₄的透明微晶玻璃,由于 Nd³⁺在热处理后富集在晶相中,使荧光光谱线在1054nm 处峰值比原始玻璃强度大．更多还原

【Abstract】 The SiO₂-Al₂O₃-P₂O₅-SiO₂ glass-ceramics which is doped neodymium was prepared by melting and the technology of crystallization.And it was characterized by DTA,XRD,fluorescence spectrometer.It indicated that the transparent glass-ceramics whose main crystal phase is AlPO₄ would be made.The temperature of nuclear generation is at the range from 490 to 590℃,and the time of treatment is about 2-4h.Then the temperature of crystallization is at the range from 600 to 700℃,and the time of treatment is about 5-7h.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 1054nm in fluorescence spectra.更多还原
