Influence of silver doping on physical properties of sprayed In2S3 films for so...
Tiss, Belgacem; Moualhi, Y; Bouguila, Noureddine; Erouel, M.; Kraini, M.; Alaya, Sahbi; Aouida, S.; Vázquez-Vázquez, C.; Moura, C.; Cunha, LuísA set of silver-doped indium sulphide (In2S3:Ag) thin films were deposited by spray pyrolysis technique, at 350 degrees C, to analyze the effects of the Ag doping on the physical properties of the films. Within the limits of the analyzed dopant concentration, X-ray diffraction (XRD) revealed the polycrystalline nature of the films, crystalizing in the beta-In2S3 cubic phase, regardless the level of doping. Both...

Tiss, Belgacem; Moualhi, Youssef; Bouguila, Noureddine; Kraini, Mabrouk; Alaya, Sahbi; Croitoru, Catalin; Ghiuta, Ioana; Cristea, Daniel; Patroi, DeliaSpray pyrolysis was used to deposit indium sulfide (In<sub>2</sub>S<sub>3</sub>) films, with or without silver doping. The films are polycrystalline, and the inclusion of Ag in the In<sub>2</sub>S<sub>3</sub> structure leads to the formation of a solid solution, with the crystallite size of the order of tens of nanometers. In<sub>2</sub>S<sub>3</sub> films exhibit a semiconductive behavior, and the incorporatio...
Electrical behavior and photocatalytic ativity of ag-doped in2S3 thin films
Tiss, Belgacem; Ben Fradj, A.; Bouguila, Noureddine; Cristea, Daniel; Croitoru, Catalin; Kraini, M.; Vázquez-Vázquez, C.; Cunha, Luís; Moura, C.Indium sulfide thin films with different amounts of silver doping were deposited by spray pyrolysis. The samples were tested as potential photocatalysts by degrading methylene blue (MB) dye aqueous solution under the effect of light. Samples were prepared using precursors with Ag/In ratios of 0 at.%, 4 at.%, and 6 at.%, corresponding to a measured and normalized Ag concentration in the films of 0.0 at.%, 1.4 at...
