Abstract
A thermochromic window doped with a dopant and a method of manufacturing the same. The thermochromic window includes a substrate and a thermochromic thin film formed on the substrate. The thermochromic thin film has a thermochromic material doped with a dopant, the concentration of the dopant gradually decreasing in a depth direction from one surface of the upper surface and the undersurface of the thermochromic thin film. The thermochromic window has a high level of visible light transmittance and high phase change efficiency while having a low phase transition temperature.
