Er3+-doped As2S3 glasses were synthesized using As, S and Er2S3 as raw materials. In order to produce glasses with high mechanical properties along with high solubility of rare earth ions in these glasses, different media such as water, hydraulics and heat-resistant oil were selected for quenching specimens. Heat-resistant oil was selected as optimized medium. The effects of Er content (0.5–2 wt%) on transmission, mechanical and structural properties of the glasses were investigated. By increasing Er content in the base glass, some clusters were introduced to glass field which causes reduction in transmission in infrared (from 70 to 25%) and visible ranges (from 70 to 60%). Density and microhardness of samples were increased from 2.78 to 3.26 g/cm3 and 81.5 to 91.75 Mpa, respectively, by increasing Er content.
