Abstract

This study is dedicated to the development of a new type of cesium tungsten bronze energy-saving laminated glass and explores its application in insulating glass combinations, offering innovative ideas and practical solutions for advancing energy-saving glass technology. Experimental results show that both Cs_xWO₃ (CWO) dispersions exhibit good visible light transmittance and near-infrared shielding properties, with CWO1 demonstrating superior shielding in the 650-950 nm range, attributed to differences in shape and size distribution and verified by simulations using the Drude-Lorentz model and the finite element method.

Keywords: energy-saving glass; finite element method; laminated glass; tungsten bronze material.
