摘　　要：通过在钠-钙-硅玻璃中添加不同质量分数的稀土元素铒熔制颜色玻璃,测量了铒着色玻璃的光谱曲线和玻璃颜色。铒在玻璃中形成稳定的3价氧化物,受熔制制度的影响较小,铒离子4f11轨道的两个同向自旋电子的基态和激发态能量比较接近,很容易吸收可见光而受到激发,使玻璃着色。The spectrum and color of soda lime glass with various content of erbium were measured.Erbium exists in stable trivalent form in the glass which is almost no affected by melting process.The electron＇s energy of ground state is close to that of excited state in the orbit 4f 11 of erbium ion,and it is easy to be excited by visual light so that the glass has been tinted.
