摘要：
Absorption and photoluminescence spectra of Sm3+ and Dy3+ doped alkali fluoroborate glasses of the composition 90.5 B2O3 + 4 AIF + 5 RF + 0.5 LnF(3) (R = Li, Na, K and Ln = Sm, Dy) are reported. On excitation. with 402 nm, the Sm3+ glasses were found to be orange fluorescent in colour and richness of that colour was high in the Na+ glass, compared to Li+ and K+ glasses, Similarly, on excitation with 398 nm, the Dy3+ glasses were fluorescent yellow and that colour was richer in the K+ glass.
