掺铒氟锆酸盐玻璃的光谱特性 OPTICAL SPECTRA OF Er 3+ -DOPED FLUOROZIRCONATE GLASS 张克立 Zhang Keli Sun Jutang Peng Zhenghe 1 first-author 孙聚堂 1 彭正合 1 武汉大学化学系 武汉大学化学系 Department of Chemistry ,Wuhan University Department of Chemistry ,Wuhan University 研究了掺铒的氟锆酸盐玻璃的电子吸收光谱、荧光发射光谱和激发光谱,并对吸收和激发谱带进行了理论计算和归属.结果表明,其激发带波长比相应吸收带波长要低2～4 nm.稀土离子Er 3+ 对玻璃的形成及其光学性质起着重要作用. In this paper,electronic absorption,fluoresceence emission and excitation spectra of Er 3+ -doped fluorozirconate glass were given.The bands of the absorption and excitation spectra were assigned.The wavelengths of the excitation bands are by 2～4nm shorter than that of corresponding absorption bands.These data indicate that the rare earth ion Er 3+ play,in the glass,an important role as structural element either for the formation or spectroscopic properties of glass. 氟锆酸盐玻璃 铒掺杂 电子吸收光谱 荧光 fluorozirconate glass Er3+-doping electronic absorption spectrum fluorescence O433 1993-04-01 2021-04-01 4
