Abstract Herein, heavy metal borate glasses activated with different concertation of Eu2O3 were prepared via the melt quench method. The Eu3+ concentration effect on photoluminescence (PL) properties of prepared glasses was investigated and discussed in detail to understand their utility in solid-state lighting and other photonic applications. The present work explains the suitability of two heavy metal oxides such as PbO and Bi2O3 for Eu2O3 doping to develop the glassy materials for photonic applications. The PL intensity was increased with an increase in Eu3+ content in PbO framed borate glasses while in Bi2O3 containing borate glasses the PL intensity was decreased at higher concentration due to concentration quenching. The Judd–Ofelt parameters and the radiative properties suggest the heavy metal borate glass hosts activated with 1 mol % of Eu3+ were potential materials for red light-emitting devices under blue light excitations. The Lifetime values of the PbO framed glasses were greater compared to Bi2O3 framed borate glasses which suggest the borate glass host containing high PbO content is more precisely suitable than Bi2O3 containing borate glass for solid-state lighting applications under blue light excitation.

含铅铋硼酸盐玻璃中 Eu3+ 离子红色光致发光的组成依赖性

摘要 本文采用熔体淬火法制备了不同配位Eu2O3活化的重金属硼酸盐玻璃。详细研究和讨论了 Eu3+ 浓度对制备的玻璃的光致发光 (PL) 特性的影响，以了解它们在固态照明和其他光子应用中的效用。目前的工作解释了两种重金属氧化物如 PbO 和 Bi2O3 对 Eu2O3 掺杂的适用性，以开发用于光子应用的玻璃材料。PL 强度随着 PbO 框架硼酸盐玻璃中 Eu3+ 含量的增加而增加，而在含有 Bi2O3 的硼酸盐玻璃中，PL 强度在较高浓度下由于浓度猝灭而降低。Judd-Ofelt 参数和辐射特性表明，用 1 mol% Eu3+ 活化的重金属硼酸盐玻璃基质是蓝光激发下红色发光器件的潜在材料。与 Bi2O3 框架硼酸盐玻璃相比，PbO 框架玻璃的寿命值更大，这表明含有高 PbO 含量的硼酸盐玻璃主体比含有 Bi2O3 的硼酸盐玻璃更适合蓝光激发下的固态照明应用。
