Abstract

In this paper, we studied the Na₂O–CaO–B₂O₃–TeO₂–Sm₂O₃ (labeled as NCBT-Sm) for the physical, optical, and luminescence properties of the NCBT-Sm glasses. The XRD study confirmed the amorphous nature of the glass. The density and molar volume increase with increasing concentration of TeO₂. We found four emission peaks located at 562, 597, 644 and 706 nm corresponding to ⁴G_5/2 → ⁶H_5/2, ⁴G_5/2 → ⁶H_7/2, ⁴G_5/2 → ⁶H_9/2 and ⁴G_5/2 → ⁶H_{1 1/2} transitions respectively. The emission and absorption spectra were analyzed using the Judd–Ofelt theory to calculate various spectroscopic parameters, such as emission cross-section, radiative transition probability, branching ratios, and stimulated emission cross-section. The color coordinates of all the glass samples lie in the orange region of the Commission International de l’Eclairage (CIE) diagram. The results obtained in the present work show that these glasses may be a potential candidate for LED applications.

玻璃原体浓度对掺Sm3+碲硼酸盐玻璃光谱和激光性能的影响

在本文中，我们研究了na20 - cao - b2o3 - teo2 - sm2o3（标记为NCBT-Sm）的NCBT-Sm玻璃的物理、光学和发光性能。XRD研究证实了玻璃的无定形性质。随着TeO2浓度的增加，密度和摩尔体积增大。在562、597、644和706 nm处发现4个发射峰，分别对应4G5/2→6H5/2、4G5/2→6H7/2、4G5/2→6H9/2和4G5/2→6H1 /2跃迁。利用Judd-Ofelt理论分析了发射光谱和吸收光谱，计算了发射截面、辐射跃迁概率、分支比和受激发射截面等光谱参数。所有玻璃样品的颜色坐标位于国际照明委员会（CIE）图表的橙色区域。本研究的结果表明，这些玻璃可能是LED应用的潜在候选者。
