Luminescence and Spectroscopic Characteristics of Zinc Barium Borotellurite Glass Doped with Tm 2 O 3 for Optical Applications

Abstract

AbstractThe conventional melt quenching procedures were followed to fabricate the samples of ZnO-BaO-B2O3-TeO2 (ZBBoT) glass doped with various concentration of Tm2O3. The consequent properties which feasible depend on the dopant were examined: density, molar volume, refractive index, absorption, and photoluminescence. The Judd-Ofelt (J-O) parameters (Ωλ, λ = 2, 4, and 6) were calculated using the absorption spectra and provided the trend of Ω2 > Ω6 > Ω4. These parameters were eventually processed to investigate the properties reflecting the appropriateness of this type of glass for optical applications. The emission spectra individually provide 2 peaks at 454, and 478 nm which are used in several optical devices.Keywords: Thulium oxideboro-tellurite glassluminescenceJ-O parametersZBBoT AcknowledgmentsThe authors would like to thank Thepsatri Rajabhat University for its warm support and Nakornpathom Rajabhat University for its fabulous facilities.
