Abstract
A thermochromic substrate and a method of manufacturing the same, in which the crystallinity of a thermochromic layer can be improved. The method includes the steps of forming a pre-thermochromic layer on a glass substrate by coating the glass substrate with pure vanadium, forming a seed layer by heat-treating the pre-thermochromic layer, and forming a thermochromic layer by coating the heat-treated seed layer with a vanadium dioxide (VO2) thin film.
