Ag semi-shell structures are capable of localized melting deformation (photothermal deformation) of the structure by laser irradiation. We observed photothermal deformation and structure-dependent spectral changes in Ag-SiO2 semi-shell structures and controlled the changes by light intensity. The results show that the semi-shell structure can change its coloration by photothermal deformation.
