Abstract: Absorption and photoluminescence spectra of Sm3+ and Dy3+ doped alkali fluoroborate glasses of the composition 90.5 B2O3 + 4 AlF + 5 RF + 0.5 LnF3 (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.
