【 摘 要 】

This research investigates the influence of the concentration of Sm+3 ions on the properties of a new borosilicate glass system with the composition 50B2O3– 14SiO2- 20Li2O– 15Na2O– 1.0Al2O3-x(Sm2O3), where × = 100, 200, 300, 400, and 500 ppm. The glasses are characterized by XRD, FTIR, UV– Vis-NIR, and photoluminescence spectra. The XRD results proved that all glasses prepared are amorphous. Moreover, it was found that the values of density (ρ), and refractive index (n), rise with increasing of Sm+3 content. Otherwise, the value of molar volume, optical energy gap, and boron-boron distance decrease by increasing Sm+3 concentration. The structure of glasses studied was investigated by computing Internuclearri, Polaron radius rp, field strength F and the deconvolution of FTIR spectra. Judd-Ofelt theory was applied to clarify the structural changes and nature of the bonds of glasses prepared. Moreover, a spectroscopic quality factor, the branching ratio (βr), and lifetime (τ) are calculated with the use of Judd-Ofelt parameters. The color chromaticity of the glasses confirmed that the emission in the white-reddish orange region under 402 nm excitation is affected by the concentration of Sm3+ ions. The results of photoluminescence emission stimulated emission cross-section, and CIE chromaticity leads to the conclusion that the glass BSLNA5 are promising candidates as laser material for light-emitting diode (LED).
