Soda-lime-silicate glasses in the compositions of (65-x)SiO2-25Na2O-10CaO-xHo2O3 (where x = 0.0, 0.50, 1.00, 1.50, 2.00 and 2.50 mol % ) were prepared by melt-quenching technique and characterized. The results show that, the absorption spectra of Ho3+ doped in soda-lime-silicate glass correspond with several bands, which are assigned from the ground state, 5I8 to 3H6 (360 nm), 5G4 (380 nm), 5G5 (417 nm), 5G6 (453 nm), 5F3 (479 nm), 5F4 (538 nm), 5F5 (639 nm), and 5I5 (880 nm). The refractive index and density of glasses were increase with increasing of Ho2O3 concentration. The color of glass samples is light amber with doped Ho2O3 in glass matrix.
