Do you know what make tungsten trioxide materials have a strong photoabsorption in a broad wavelength range of the NIR region? It is the unusual oxygen defect structure and strong local surface plasma resonance (LSPR) of tungsten trioxide materials that offer strong photoabsorption in a broad wavelength range of the NIR region. In the past, several light-absorbing nanomaterials such as noble metals, polymeric materials, and other inorganic nanomaterials were of interest for their use in photothermal therapy for cancer treatment. In this process, as a new type of photothermal material, the synthesis, properties, and applications of tungsten trioxide nanomaterials are well-studied. In addition, recent progress in various fields such as NIR light-shielding, pyroelectric, water evaporation, photocatalysis, gas sensors, and energy-related applications for WO3 nanomaterials are highlighted.
