Preparation and physical properties of strontium barium phosphate glasses dope with praseodymium

Abstract

In this research, studies the physical properties of the strontium barium phosphate glasses with varied the concentration of Pr2O3. Glass samples were prepared by melt – quenching technique at 1200 °C. The results found that all glass samples are clear, homogenous and transparent. The density and refractive index of glass samples were increased with increasing Pr2O3 concentration, while the molar volume trend to decreased when the Pr2O3 concentration doped in glasses is increased. In addition, when doped the praseodymium oxide in glass will not affect the Vickers hardness of barium phosphate glasses.
