Abstract

This study aims to determine the effect of neodymium concentration on barium sodium borate glasses. The glass samples were fabricated using the melt-quenching technique for analyzing the physical properties, absorption spectra, and NIR emission spectra. The twelve absorption bands increased with the increase in Nd3+ concentration. The most intense absorption band is centered at 583 nm (corresponding to the 4I9/2→4G5/2 transition), which is chosen to investigate the NIR emission spectra. The NIR emission spectra exhibited the most intense emission band at 1,077 nm under 583 nm excitation wavelength, corresponding to the 4F3/2→4I11/2 transition, respectively. The maximum NIR emission intensity was observed at the glass sample with 2 mol% of Nd3+. The NIR emission spectra and the results from Judd-Ofelt theory confirm that 2 mol% of Nd3+-doped Ba-Na-B glasses with a 1,077 nm emission in this work might be used as an NIR laser medium material.

开发掺杂 nd3+ 的硼酸盐玻璃,用于高效 nir 激光介质材料
本研究旨在确定钕浓度对硼酸钡钠玻璃的影响。采用熔融淬火技术制作了玻璃样品,并对其物理性质、吸收光谱和近红外发射光谱进行了分析。随着 Nd3+ 浓度的增加,十二条吸收带也随之增加。最强烈的吸收带集中在 583 nm 处(对应于 4I9/2→4G5/2 转变),我们选择该吸收带来研究近红外发射光谱。在 583 nm 激发波长下,近红外发射光谱在 1,077 nm 处显示出最强烈的发射带,分别对应于 4F3/2→4I11/2 转变。在含有 2 mol% Nd3+ 的玻璃样品中观察到了最大的近红外发射光谱强度。近红外发射光谱和 Judd-Ofelt 理论的结果证实,本研究中掺有 2 mol% Nd3+ 的 Ba-Na-B 玻璃可用作近红外激光介质材料,其发射波长为 1,077 nm。
