Development of Sm3Â + doped ZnO-Al2O3-BaO-B2O3 glasses for optical gain medium

Sm3 + doped ZnO-Al2O3-BaO-B2O3 glasses have been prepared and characterized. These glasses have been developed by melt and quenching technique. The characterization includes the physical, optical, luminescence, and radiative properties. The lasing potential of glass samples such as oscillator strengths, JO parameter, stimulated emission cross-sections, radiative transition probability, and branching ratios have been calculated by using Judd-Ofelt theory. The results show that the maximum intensity of emission spectra of the prepared glass sample is at the wavelength of 598 nm due to the 4G5/2 → 6H7/2 transition, excited by λex = 403 nm. From CIE 1931 chromaticity, the title glasses were found to be a potential material for laser application in the orange region.
