【摘要】 钨掺杂二氧化钒（W-VO₂）具有低的半导体-金属相变温度，在智能窗领域具有很大的应用潜力。但是其可见光透过率(T_lum)和太阳调制能力(ΔT_sol)相对较低，不断提高T_lum和ΔT_sol一直是智能窗领域研究的热点。本文提出，通过旋涂方法在玻璃基板表面制作W-VO₂/PMMA/W-VO₂法布里-珀罗腔结构，通过改变W-VO₂体积分数及介质层厚度，增强热致变色性能。结果表明，这一结构的ΔT_sol可以提高至15.61%,T_lum维持在37.01%。研究结果有利于提升VO₂在智能窗中的应用。更多还原

【Abstract】 Tungsten-doped vanadium dioxide （W-VO₂） exhibits a low semiconductor-metal phase transition temperature,and holds significant potential in smart windows.However,its visible light transmittance (T_lum) and solar modulation capability (ΔT_sol) are relatively constrained.The continuous improvement of T_lum andΔT_sol has been a focal point in research.In this paper,we propose a W-VO₂/PMMA/W-VO₂Fabry-Pérot cavity structure to enhance thermochromic performance.The results reveal that the solar modulation capability of this structure can be elevated to 15.61%,while maintaining a visible light transmittance of 37.01%.These outcomes hold the potential to facilitate the application of VO₂nanoparticles in smart windows.更多还原
