Smart materials that reversibly change color upon light illumination are widely explored for diverse appealing ***,light-responsive color switching materials are mainly limited to organic *** synthesis of inorganic counterparts has remained a significant challenge because of their slow light response and poor ***,we report a seeded growth strategy for the synthesis of TiO_(2-x)/WO_(3)·0.33H_(2)Ohetero-nanoparticles(HNPs)with networked wire-like structure of〜10 nm in diameters that enable the highly reversible light-responsive color switching *** the TiO_(2-x)/WO_(3)·0.33H_(2)OHNPs,T P species self-doped in TiO_(2-x)nanoparticles(NPs)act as efficient sacrificial electron donors(SEDs)and Ti-O-W linkages formed between TiO2-x and WO30.33H2O NPs ensure the nanoscale interfacial contact,endowing the HNPs enhanced photoreductive activity and efficient interfacial charge transfer upon ultraviolet(UV)illumination to achieve highly efficient color *** TiO_(2-x)/WO_(3)·0.33H_(2)OHNPs exhibits rapid light response(180 times).We further demonstrate the applications of TiO_(2-x)/WO_(3)·0.33H_(2)O HNPs in ink-free,light-printable rewritable paper that can be written on freehand or printed on through a photomask using UV *** work opens an avenue for designing inorganic light-responsive color switching nanomaterials and their smart applications.
