Tri–positive rare earth ions activated alkali heavy metal borate glasses were designed and synthesised using melt–quenching process. Photoluminescence (PL), nonlinear optical (NLO), and optical limiting (OL) attributes of titled glasses have been systematically investigated in order to understand the efficacy of tri–valent europium ions and the obtained results are discussed in detail. The PL attributes were assessed with the blue light pumping. The NLO and OL features were evaluated in 700–1000 nm spectral region using femtosecond laser pulses. The two–photon absorption and nonlinear refractive index coefficients were found to be increased with elevation of Eu₂O₃ content to higher doping whereas the OL threshold factors exhibited an opposite behaviour. The PL and Judd–Ofelt analysis revealed the glass matrices containing high concertation of tri–valent europium ions are more useful for red lighting applications when excited with blue light. NLO and OL results suggest the strong Eu³⁺ containing glasses are ideal materials for designing optical limiters of high power to work in near infrared region with femtosecond pulses.

使用熔融淬火工艺设计并合成了三正稀土离子活化碱金属重金属硼酸盐玻璃。为了了解三价euro离子的功效，系统地研究了标题玻璃的光致发光（PL），非线性光学（NLO）和光学限制（OL）属性，并详细讨论了获得的结果。PL属性通过蓝光泵浦进行评估。使用飞秒激光脉冲在700–1000 nm光谱范围内评估了NLO和OL特征。发现随着Eu ₂ O _3的升高，双光子吸收系数和非线性折射率系数增加含量高于较高的掺杂量，而OL阈值因素表现出相反的行为。PL和Judd-Ofelt分析表明，当蓝光激发时，含有高度一致的三价concert离子的玻璃基质对于红色照明应用更为有用。NLO和OL结果表明，含强Eu ³⁺的玻璃是设计高功率光学限制器的理想材料，该限制器可在飞秒脉冲的近红外区域工作。
