摘要

二氧化碳等各种杂质气体影响氢能的利用，存在一定的安全问题。因此，设计能够连续发射并覆盖宽光谱杂质气体的超宽中红外玻璃作为红外荧光光源是一种环保策略。本研究通过在Cs2ZnCl4基体中掺杂稀土离子Er3+/Ho3+/Dy3+，并将其植入氟化玻璃基体中，成功实现了高效的宽带中红外发射。中红外发射的半最大值全宽度（FWHM）从255 nm明显扩大到426 nm，显示出优异的热稳定性，突出了Cs2Zn1-x-yErx(Ho/Dy)yCl4-ZBLAN无铅钙钛矿氟化玻璃作为中红外光源的独特优势。基于Cs2Zn1-x-yErx(Ho/Dy)yCl4-ZBLAN钙钛矿氟化玻璃，设计了一种简便的氢杂质气体测量装置。这为扩大中红外光源和气体纯度测量的应用范围提供了广阔的思路。

Ultra-broad mid-infrared emission from Cs2Zn1-x-yErx (Ho/Dy)yCl4 fluoride glasses by lattice distortion for carbon dioxide detection in hydrogen energy

Various impurity gases such as carbon dioxide affect the utilization of hydrogen energy and have certain safety problems. Therefore, It is an environmentally friendly strategy to design ultra-wide mid-infrared glass that can continuously emit and cover a wide spectrum of impurity gases as an infrared fluorescent light source. Here, we successfully achieved efficient broadband mid-infrared emission by doping rare earth ions Er³⁺/Ho³⁺/Dy³⁺ in the Cs₂ZnCl₄ matrix and implanting it in a fluoride glass matrix. The Full Width at Half Maximum (FWHM) of the mid-infrared emission is significantly broadened from 255 nm to 426 nm, showcasing the exceptional thermal stability and underscoring the unique advantages of Cs₂Zn_1-x-yEr_x(Ho/Dy)_yCl₄-ZBLAN lead-free perovskite fluoride glass as a mid-infrared light source. Based on Cs₂Zn_1-x-yEr_x(Ho/Dy)_yCl₄-ZBLAN perovskite fluoride glass, a convenient device for measuring impurity gas in hydrogen was designed. This provides a broad idea for expanding the application range of mid-infrared light sources and gas purity measurement.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
