In this paper, heavy metal oxide glasses based on bismuth, germanate and gallium elements doped with Er3+ have been synthesized. Composition of glass matrix has been developed in terms of low phonon energy (724 cm-1), low absorption coefficient in the infrared region (1.2 cm-1), good mechanical and chemical properties. Synthesis of glasses has been performed under a low vacuum condition, which has reduced the OH- ions to 50 ppm. Glasses were doped with (0.25 – 1 mol%) Er2O3 to obtain emission at the wavelength of 2.7 μm (4I11/24I13/2) under 980 nm laser diode excitation. Obtained results demonstrate that developed heavy metal oxide glass is an attractive material for mid-infrared applications.
