Abstract

A series of glass ceramic samples precipitated with Ca₂(Mg_0.5Al_0.5)(Si_1.5Al_0.5O₇): Yb³⁺, Er³⁺ nanoparticles were synthesized by the melt quenching method to effectively recycle blast furnace slag. Their structures, morphologies, and luminescent properties were comprehensively investigated using X-ray diffraction, transmission electron microscopy, and photoluminescence, respectively. The impact of adding Al₂O₃/SiO₂ to the blast furnace slag raw material on the transmittance, hardness, and luminescent properties of the glass-ceramics was analyzed. Upon excitation with a 980 nm laser, all glass-ceramic samples emitted strong Er³⁺ upconversion luminescence at 526, 549, and 650 nm. Moreover, the addition of Yb³⁺ ions significantly enhanced the luminescent intensity. A dual-mode temperature sensor based on fluorescence intensity ratios was realized using a single luminescent center. All results indicate that the glass ceramic samples prepared from blast furnace slag are potentially promising for self-referential optical temperature measurement.

基于高炉渣玻璃陶瓷的双模光学测温仪

用 Ca2(Mg0.5Al0.5)(Si1.5Al0.5O7)沉淀的一系列玻璃陶瓷样品：Yb3+, Er3+ 纳米粒子的玻璃陶瓷样品。分别利用 X 射线衍射、透射电子显微镜和光致发光对其结构、形貌和发光特性进行了全面研究。分析了在高炉矿渣原料中添加 Al2O3/SiO2 对玻璃陶瓷的透射率、硬度和发光特性的影响。在 980 纳米激光的激发下，所有玻璃陶瓷样品都在 526、549 和 650 纳米波长处发出强烈的 Er3+ 上转换发光。此外，加入 Yb3+ 离子后，发光强度明显增强。利用单个发光中心实现了基于荧光强度比的双模式温度传感器。所有结果都表明，用高炉矿渣制备的玻璃陶瓷样品有望用于自反射光学温度测量。

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.
