Enhanced UV photo-detection properties of graphene oxide incorporated transparent TiO2 thin films in Schottky configuration

Structural, optical, and morphological evaluation of PVA/Bi-Ni oxide-rGO nanocomposite casted films for optical devices applications

“…Recently, PVA system doped with graphene or its derivatives (graphene oxide (GO) and reduced GO (rGO)) have been studied and concluded that the GO/rGO improves the absorbance of the PVA film and reduces its optical bandgap energy [22][23][24]. Loading the polymer composite system with a small amount of graphene material enhances the matrix properties [25], besides improving the photochemical stability of the matrix that is combined with it [26][27][28][29]. Besides, the Ni ions are characterized by their unique optical properties, as the metal oxides doped with Ni ions causes an enhancement in their photocatalytic activity and the photo response of the material by preventing charge carriers from recombining on the photocatalyst's surface [30,31].…”

Porosity-dependent photoelectrochemical activity of double-layered TiO2 thin films deposited by spin-coating method

“…Metal oxide-based semiconductor thin lms are frequently employed in industrial applications due to their versatility, simplicity of fabrication, abundance, and low cost. Among them, TiO 2 thin lms are particularly popular because they can be utilized for the development of thin lm-based solar cells, 1,2 gas sensors, 3,4 UV detection, 5,6 UV screening and protection of solar cells, 7 superhydrophilic coatings, 8,9 photocatalytic degradation of organic pollutants, 10,11 photoelectrochemical (PEC) water splitting, 12,13 etc. In general, the efficiency of solar cells, gas sensing devices, photocatalytic, and photoelectrochemical devices is strongly dependent on interfacial contact area, i.e.…”
