Abstract

The work focuses on developing new alternative radiation shielding and visible luminescent glasses from (55-x) SiO2: 13B2O3: 1Al2O3: 4.5BaO: 6.3CaO: 0.2Sb2O3: 20Na2O:xPr2O3 where x = 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mol% composition. Glasses have been fabricated by melt-quenching technique. Four emission bands at 484 nm, 528 nm, 605 nm, and 645 nm were observed. Highest emission intensity is observed for 1.0mol% of Pr3+ ions whereas radiation shielding ability showed better results for higher concentration of Pr3+ ions. Prominent blue emission around 482 nm is been strong in the present glasses. The radiation shielding properties have been evaluated and results show that all glass samples are better radiation shielding properties than ordinary concrete, red brick, and commercial windows.
