摘要：

Glasses with composition (in mol %), 32 ZnF2, 28 CdF2, 20 BaF2, 11 LiF, 5 AlF3, 4 LaF3 have been prepared and doped with some 4f ions (Ho3+, Tm3+, Er3+). The energy levels and oscillator strengths of the electronic transitions have been obtained. Using the Judd-Ofelt theory, the radiative transition probabilities between the different levels were calculated. We have measured the emission bands and lifetimes and determined the non-radiative transition rates, the luminescence efficiencies and the emission cross-sections of some "laser transitions". The optical properties of this new material are slightly improved with respect to those of the fluorozirconate glasses.
