Heat-insulating clear coatings have been widely studied and used in energy conservation of buildings. In this article, tungsten-doped tin dioxide (WTO) nanoparticles were synthesized by a facile hydrothermal approach. The effects of molar doping ratios of tungsten, calcination temperatures of the WTO precursor, and hydrothermal synthesis temperatures on the phase composition and optical properties of WTO powder were investigated. The conditions for the preparation of WTO with better optical properties are as follows: the hydrothermal temperature is 180 °C, the molar doping ratio of tungsten is 1%, and the hydrothermal product is calcined at 900 °C. A possible mechanism of the optical properties of nano-WTO powder was proposed, in which tungsten ions provide carriers for tin oxide. It is worth mentioning that this is the first report on the synthesis of WTO nanoparticles and the development of their near-infrared light shielding properties.

钨掺杂二氧化锡纳米粒子的近红外屏蔽性能

隔热透明涂料在建筑节能方面得到了广泛的研究和应用。在本文中，钨掺杂二氧化锡 (WTO) 纳米粒子通过简便的水热法合成。研究了钨的摩尔掺杂比、WTO前驱体的煅烧温度和水热合成温度对WTO粉末的相组成和光学性能的影响。制备光学性能较好的WTO的条件为：水热温度180℃，钨的摩尔掺杂比为1%，水热产物900℃煅烧。提出了一种可能的纳米WTO粉末光学性质的机制，其中钨离子为氧化锡提供了载体。
