Abstract

Near Infrared (NIR) shielding is a challenging issue in developing novel technology for smart building applications. Tungsten bronze-based material is one of the interesting materials for IR absorption and shielding applications. This research work aims to conduct the facile synthesis of sodium tungsten bronze powder (Na_xWO₃) via a high energy ball milling technique. The effect of ball milling time on the properties of the prepared product was investigated by relevant characterization techniques including X-ray diffraction technique, electron microscopy, X-ray photoelectron spectroscopy, and UV–vis–NIR spectrophotometry. At certain milling of 2–3 h, the corresponding results exhibited the phase transformation from starting precursor to the Na₀_·₃WO₃ phase with good near-infrared absorptivity due to localized surface plasmon resonance phenomena of this phase.

一步球磨法合成的钨青铜钠颗粒的结构及可见-近红外光学性能

近红外（NIR）屏蔽是智能建筑应用新技术开发中的一个具有挑战性的问题。钨青铜基材料是红外吸收和屏蔽应用的热门材料之一。本研究的目的是利用高能球磨技术快速合成钠钨青铜粉（NaxWO3）。采用x射线衍射、电子显微镜、x射线光电子能谱、紫外-可见-近红外光谱等表征技术研究了球磨时间对产物性能的影响。在一定的研磨时间2 ~ 3 h下，由于Na0·3WO3相的局部表面等离子体共振现象，导致该相从起始前驱体转变为具有良好近红外吸收率的Na0·3WO3相。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
