Abstract: In this work, Na2O-Al2O3-BaO-CaO-Sb2O3-B2O3-SiO2 glasses doped with Er3+ was prepared and investigated for their physical, optical and visible luminescence properties. The increases in density, refractive index and molar volume of the glasses with additional doping content of Er2O3 into the network were due to a higher molecular weight and polarizability of Er2O3 in comparison with the glass former (SiO2 and B2O3). Ten absorption peaks were observed as a nature of Er3+ absorption in glass matrices. The glass exhibited four emission transitions which were assigned to 4F5/24I15/2 (460 nm), 4F7/24I15/2 (487 nm), 2H11/24I15/2 (522 nm) and 4S3/24I15/2 (545 nm) transitions. The strongest intensity was the green emission at 522 nm. The luminescence intensity was found to increase with Er2O3 content up to 4 mol% and it was decreased for higher Er2O3 contents due to concentration quenching effect.
