Problems solved by technology

However, the visible light transmittance of the coating prepared by this technology is too low, even less than 60%.
[0017] Although many preparation methods of vanadium dioxide and doped vanadium dioxide coatings have been reported, such as chemical vapor deposition, reactive evaporation, magnetron sputtering, laser pulse deposition, sol-gel method, hydrothermal Synthesis method, vacuum reduction method, spray pyrolysis method, etc., but these methods have expensive raw mat
