Abstract

In this study, spectrally selective coating with improved near-infrared shielding property was fabricated by direct spray technique using the Cs0.33WO3 and Sb-doped SnO2 as composite filler. The effect of Cs/W molar ratio on phase composition, crystal structure, morphology, chemical state and optical property was investigated. The results reveal that the Cs/W molar ratio has a significant influence in promoting the form of hexagonal crystal structure, which is beneficial to improve spectral selectivity. Especially, when the Cs/W molar ratio was 0.375, the as-synthesized Cs0.33WO3 product demonstrated the desired phase composition and W5+ generation. Furthermore, the spectrally selective coating prepared by the dispersion with 10 wt% composite filler combined with Cs0.33WO3 and Sb-doped SnO2 presented optimal optical performance. The excellent near-infrared shielding performance of the spectrally selective coating indicates great potential in the field of energy-efficient glazing.
