【摘要】 分析表明,Na₂O-B₂O₃-SiO₂系AgX（X=Br^-,Cl^-）光色玻璃的Raman光谱由SiO₁四面体、四硼酸盐基团、二硼酸盐基团和硼氧环等的振动构成。热处理改变玻璃显微结构及AgX大小,但不改变玻璃结均基团的类型。少量AgX固溶体的存在没有被Raman光谱检测出来。更多还原

【Abstract】 Analysis results indicate that the Raman spectra of AgX （X=Br^-, Cl^-）containing photochromic glasses in the Na₂O-B₂O₃-SiO₂ system consist of the vibrations of SiO₄ tetrahedra, tetraborate groups, diborate groups and boroxol groups.It is obvious that heat treatment changes the microstructure of the glasses and the size of AgX, but not the type of the structural groups. A small amount of AgXss presented in the glasses can not be detected by Raman spectroscopy.更多还原
