Abstract

A shell size adjustable core–shell nano building block of SiO2@TiO2 using high refractive index materials of TiO2 as shell to coat SiO2 colloidal NPs by one step approach was prepared. Corresponding colloidal suspension of SiO2@TiO2 photonic crystals in propylene carbonate showed a highly adjustable structure color change with the high-refractive index upon applying of electric fields.
