The aim of the work is to prepare (51-x)BO + 23CaF + 10LiO + 10NaO + 6BaO + xEuO glasses with various concentration, analyse the optical/radiative properties and compare with other reported literature. In this work, the Judd-Ofelt analysis was employed to evaluate oscillator strength, JO parameters. Using JO parameters, radiative properties of the prepared samples were evaluated to understand their branching ratios, stimulated emission cross-section and radiative lifetime. The phonon coupling constant was evaluated using phonon sideband and compared with other literatures. The present glasses doped with Eu ions find a potential use in orange red light emitting optical display device applications.
这项工作的目的是制备具有不同浓度的(51 - x)BO + 23CaF + 10LiO + 10NaO + 6BaO + xEuO玻璃，分析其光学/辐射特性，并与其他已报道的文献进行比较。在这项工作中，采用Judd-Ofelt分析来评估振子强度、JO参数。利用JO参数，评估了所制备样品的辐射特性，以了解其分支比、受激发射截面和辐射寿命。利用声子边带来评估声子耦合常数，并与其他文献进行比较。目前掺杂Eu离子的玻璃在橙红色发光光学显示器件应用中具有潜在用途。
