This paper reports on the absorption and emission spectra o of RE{sup 3+} (= Nd{sup 3+} or Er{sup 3+}) doped Bi{sub 2}O{sub 3}-B{sub 2}O{sub 3}-LiF (Bi-B-LiF) glass system. The absorption spectrum of Nd{sup 3+} doped Bi-B-LiF glass has exhibited eight absorption bands at 513 nm, 525 nm, 584 nm, 626 nm, 682 nm, 748 nm, 805 nm and 876 which correspond to the electronic transitions of ({sup 4}I{sub 9/2}{yields}{sup 4}G{sub 9/2}), ({sup 4}I{sub 9/2}{yields}{sup 4}G{sub 9/2}, {sup 4}G{sub 7/2}), ({sup 4}I{sub 9/2}{yields}{sup 4}G{sub 5/2}, {sup 2}G{sub 7/2}), ({sup 4}I{sub 9/2}{yields}{sup 2}H{sub 11/2}), ({sup 4}I{sub 9/2}{yields}{sup 4}F{sub 9/2}), ({sup 4}I{sub 9/2}{yields}{sup 4}F{sub 5/2}, {sup 4}S{sub 3/2}), ({sup 4}I{sub 9/2}{yields}{sup 4}F{sub 5/2}, {sup 2}H{sub 9/2}) and ({sup 4}I{sub 9/2}{yields}{sup 4}F{sub 5/2}) respectively. From Nd{sup 3+} : Bi-B-LiF glass, three NIR emission bands have been observed at 900 nm, 1075 nm and 1342 nm, which are assigned to the transitions of ({sup 4}F{sub 3/2}{yields}{sup 4}I{sub 9/2}), ({sup 4}F{sub 3/2}{yields}{sup 4}I{sub 11/2}) and ({sup 4}F{sub 3/2}{yields}{sup 4}I{sub 13/2}) respectively with an excitation at 514.5 nm (Ar{sup +} ion laser). The Er{sup 3+} : Bi-B-LiF glass has revealed six absorption bands at 489 nm, 522 nm, 653 nm, 800 nm, 973 nm and 1531 nm which are labeled to the transitions of ({sup 4}I{sub 15/2}{yields}{sup 4}F{sub 7/2}), ({sup 4}I{sub 15/2}{yields}{sup 2}H{sub 11/2}, 4G{sub 11/2}), ({sup 4}I{sub 15/2}{yields}{sup 4}F{sub 9/2}), ({sup 4}I{sub 15/2}{yields}{sup 4}I{sub 7/2}), ({sup 4}I{sub 15/2}{yields}{sup 4}I{sub 11/2}), and ({sup 4}I{sub 15/2}{yields}{sup 4}I{sub 13/2}) respectively. From the Er{sup 3+}: Bi-B-LiF glass, an NIR emission at 1540 nm ({sup 4}I{sub 13/2}{yields}{sup 4}I{sub 15/2}), has been observed with an excitation at 514.5 nm (Ar{sup +} ion laser).
