The transition metal oxide (TMO) film, VO2, was fabricated on Ag doping titanium oxide substrates by sol-gel method. By the measurement of in-plane resistance varied with temperature under ultraviolet light irradiation, an obvious decrease in the phase transition temperature point was observed for VO2/TiO2 with a silver hierarchical configuration. The reason why the phase transition temperature point shift was discussed base on the voltage measurement under light irradiation that indicated hole-carrier injection from the substrate to the VO2 film. The TMO film could be applied as a photo-thermochromic smart window to enable automatic solar/heat control in response to environmental temperature and solar light.
