Abstract

Phosphate glasses have garnered significant attention as host materials for various laser applications due to their high rare-earth ion solubility, large stimulated emission cross-section, and low nonlinear refractive index. Modification of phosphate glass composition is feasible through poly-anion substitution, leading to poly-anionic glasses with unique properties. This study explores the glass-forming regions (GFRs) of AlF₃-R₂SO₄-M(PO₃)₂-based poly-anionic fluoro-sulfo-phosphate (R/M-FSP) glasses, a promising class of ionic glasses. Theoretical GFRs are predicted using a thermodynamic approach and then validated through a few experiments. The experimental GFRs range from K/Ba-FSP > Na/Ba-FSP > Li/Ba-FSP > K/Sr-FSP > Na/Sr-FSP > Li/Sr-FSP, with wider areas observed under lower cation field strength. Notably, the K/Ba-FSP glass system exhibits high anti-crystallization stability (approximately 140°C) and a low nonlinear refractive index (1.43 × 10^–13–1.83 × 10^–13 esu), advantageous for high-power laser operations. Furthermore, a comparative study among K/Ba-FSP glasses elucidates the general principles of manipulating glass structure and physical properties through compositional variation.

AlF3-M(PO3)2-R2SO4 基多阴离子氟磺磷酸盐玻璃中玻璃形成区的预测

磷酸盐玻璃具有稀土离子溶解度高、受激发射截面大和非线性折射率低的特点，因此作为各种激光应用的主材料备受关注。通过多阴离子置换可以改变磷酸盐玻璃的组成，从而产生具有独特性质的多阴离子玻璃。本研究探讨了基于 AlF3-R2SO4-M(PO3)2 的多阴离子氟硫磷酸盐（R/M-FSP）玻璃的玻璃形成区（GFR），这是一类很有前途的离子玻璃。我们采用热力学方法预测了理论 GFRs，并通过一些实验进行了验证。实验得出的 GFR 范围包括 K/Ba-FSP > Na/Ba-FSP > Li/Ba-FSP > K/Sr-FSP > Na/Sr-FSP > Li/Sr-FSP，在阳离子场强较低的情况下，观察到的区域更宽。值得注意的是，K/Ba-FSP 玻璃系统具有较高的抗结晶稳定性（约 140°C）和较低的非线性折射率（1.43 × 10-13-1.83 × 10-13 esu），有利于高功率激光操作。此外，对 K/Ba-FSP 玻璃的比较研究阐明了通过成分变化操纵玻璃结构和物理性质的一般原理。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
