A method for manufacturing a chemochromic nanoparticle, the method comprising:
- preparing a hydrated or non-hydrated transition metal oxide;
- preparing a metal catalyst solution by dissolving a metal catalyst precursor and a polymer compound in an organic solvent;
- preparing a mixed solution by adding the hydrated or non-hydrated transition metal oxide to the metal catalyst solution;
- manufacturing the chemochromic nanoparticle with a core-shell structure by irradiating UV light to the mixed solution;
- and
- obtaining the chemochromic nanoparticle by filtering the mixed solution,
- wherein the chemochromic nanoparticle is formed in a core-shell structure.
