Abstract

Near-infrared (NIR) shielding properties are important for solar films. In this study, Cs_xWO₃ films prepared using electron beam evaporation were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, and spectrophotometry. The effects of annealing on NIR shielding properties and film microstructure were investigated. The results show that the NIR shielding properties of Cs_xWO₃ films can be improved by annealing at 300-450°C under pure H₂ atmosphere, the amorphous thin films being transformed to crystalline films. The Cs_xWO₃ films annealed at 450°C in pure H₂ atmosphere showed high transmittance of visible light (70%) and high NIR shielding ratio (99%).
