摘要：
The fluorescence spectra of Sm, Sm + Ho, Eu and Eu + Ho doped in calibo and silicate glasses at 300 and 77 K have been recorded in the visible region as excited by the different lines of an Ar+ laser. Stark components of a few levels involved in the observed transitions in Sm3+ and Eu3+ resolved. The change in the intensity of the spectral lines of Sm3+ and Eu3+ in the presence of Ho3+ in the same glass has also been studied.
