The samarium-doped lithium-gadolinium-borate glasses [60Li 2 O:10Gd 2 O 3 :(30-x) B 2 O 3 :xSm 2 O 3 ] where x = 0.05, 0.10, 0.50, 1.00 and 1.50 mol% and zinc-barium-borate glasses [(60-x)B 2 O 3 :30BaO:10ZnO: xSm 2 O 3 ] where x= 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol% have been prepared by the same method. The absorbtion spectra are similar in transitions from the ground state 6 H5/2 to the excited states with minor difference. Both glass system gave the emission spectra with peaks at 562, 600, 646, 707 nm arise from the transition 6 H 5/2 , 6 H 7/2 , 6 H 9/2 , and 6 H 11/2 respectively, under 404 nm excitetation ligth. The concentration quenching effect (CQE) was found at 1.0 mol% of the dopant for LGBO: Sm 3+ , due to not observed for ZBaB: Sm 3+. Both glass systems doped with Sm 3+ .
