A series of different modifiers infused Dy³⁺ ions doped Alkali lead bismuth borate glasses were synthesized and their potential for photonic applications were analyzed through some mandatory characterizations like XRD, FTIR, Raman, optical absorption, photoluminescence and decay measurements. In this work, effort was taken to show the structural differences that occur in the host network when different modifiers were introduced into it. Amorphous nature of all the glasses was proven with XRD profile and the absorption of Dy³⁺ ions to different excited states was observed. The Judd-Ofelt (JO) parameters for the glasses follows the trend as Ω₂> Ω₄> Ω₆ and from the luminescence spectra, emissions corresponding to blue (⁴F_9/2→ ⁶H_15/2), yellow (⁴F_9/2→⁶H_13/2) and red (⁴F_9/2→⁶H_11/2) color were observed while exciting the prepared glasses at 387 nm. Radiative parameters like transition probability, stimulated emission cross-section, branching ratios and radiative lifetime were calculated using JO parameters and refractive index values. Yellow to blue intensity ratio (Y/B), CIE chromaticity coordinates and correlated color temperature (CCT) values are calculated using the emission spectra to evaluate the emitted light. The obtained CIE values were found to be in excellent proximity with the standard white light (0.33, 0.33). The lifetime of the ⁴F_9/2 excited state was measured and found to exhibit non-exponential behavior. The obtained results suggest the utility of the glasses for potential w-LED applications.

合成了一系列不同的改性剂注入 Dy ³⁺离子掺杂碱金属硼酸铅铋玻璃，并通过一些强制性表征（如 XRD、FTIR、拉曼、光吸收、光致发光和衰减测量）分析了它们在光子应用中的潜力。在这项工作中，我们努力展示了在主机网络中引入不同修饰符时发生的结构差异。所有玻璃的非晶性质都通过 XRD 谱证明，并观察到Dy ³⁺离子对不同激发态的吸收。眼镜的 Judd-Ofelt (JO) 参数遵循趋势为 Ω ₂ > Ω ₄ > Ω ₆从发光光谱，发射对应于蓝色 ( ⁴ F _9/2 → ⁶ H _15/2 )、黄色 ( ⁴ F _9/2 → ⁶ H _13/2 ) 和红色 ( ⁴ F _9/2 → ⁶ H _{11 ) /2}) 在 387 nm 激发制备的玻璃时观察到颜色。使用 JO 参数和折射率值计算辐射参数，如跃迁概率、受激发射截面、分支比和辐射寿命。使用发射光谱计算黄色与蓝色强度比 (Y/B)、CIE 色度坐标和相关色温 (CCT) 值以评估发射光。发现获得的 CIE 值非常接近标准白光 (0.33, 0.33)。测量了⁴ F _9/2激发态的寿命并发现其表现出非指数行为。获得的结果表明玻璃在潜在 w-LED 应用中的实用性。
