Enhancement of optoelectronic properties of TiO2 films containing Pt nanoparticles

Enhancement of optoelectronic properties of TiO2 films containing Pt nanoparticles

Anatase TiO2 and TiO2 films containing Pt nanoparticles were prepared by sol–gel dip coating method and characterized by X-ray diffraction (XRD), atomic force microscopy, scanning electron microscopy and transmission electron microscopy. Further, optoelectronic properties were investigated, showing...
