Abstract

(LiO)(SrO)(NdO)(BO)(GdO), where = 0, 3, 5, 7, and 10 mol%, glass was melt-quenched to test it as a laser source in the near-infrared (NIR) region. The structural modification, absorption spectra, Judd-Ofelt (J-O) parameters, luminescence spectra, radiative laser parameters, lifetimes, XRD, and FTIR spectra were studied. Luminescence spectra excited at = 584 nm revealed the highest intensity peak at 1073 nm due to the transition of F → I. An important phenomenon of concentration quenching was observed and optimized luminescence was achieved with the sample having the concentration = 07 mol%. The lifetimes of the donor and acceptor and energy transfer from gadolinium to neodymium were obtained from the luminescence decay kinetics. The findings show that Nd-doped GdO-modified glass materials have potential as NIR laser sources.

摘要

（LiO）（SrO）（NdO）（BO）（GdO），其中 = 0、3、5、7和10摩尔％，将玻璃进行熔体淬火以测试其作为近红外（NIR）区域激光源的性能。研究了结构改性、吸收光谱、贾德 - 奥费尔特（J - O）参数、发光光谱、辐射激光参数、寿命、X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）。在 = 584 nm激发下的发光光谱显示，由于F → I跃迁，在1073 nm处有最高强度峰。观察到了浓度猝灭这一重要现象，并且浓度 = 07摩尔％的样品实现了优化发光。从发光衰减动力学获得了施主和受主的寿命以及从钆到钕的能量转移。研究结果表明，掺钕的GdO改性玻璃材料具有作为近红外激光源的潜力。
