Thin nanocrystalline TiO2–SnO2 sprayed films: Influence of the dopant concentration, substrate and thermal treatment on the phase composition and crystallites sizes

Structural and morphological characterization of TiO2-SnO2 thin film prepared by combining doctor-blade and sol-gel techniques

“…The (110), (101) and (211) planes at 2θ values 27, 34.1 and 53 degrees were observed as the characteristic peaks of SnO2 in the doped TiO2 film. The similar results have also been reported in the previous studies [11][12][13].…”

“…This feature gives a more stable chemical bond and permits excellent interconnection and continuity between titania nanoparticle, which in turn enhances electron transfer efficiency in photoanode [3][4]. This phenomenon showed that the inclusion of SnO2 in the TiO2 may stabilize the anatase as the main and strongest phase [5,13]. The smaller radius of Ti 4+ (0.68 Å) as compared to Sn 4+ (0.69 Å) [5] also made the crystallite size of doped TiO2 film is bigger than the undoped one.…”

Nanostructured thin film of iron tin oxide by aerosol assisted chemical vapour deposition using a new ferrocene containing heterobimetallic complex as single-source precursor

“…Gas sensors made from these hybrid composite materials by doping method have a lower operating temperature and sensitivity due to an enhanced surface-tovolume ratio [15]. Structural changes associated with doping mainly depend on the method of synthesis of these composite materials [16]. Iron doped tin oxides have been reported using different techniques, viz.…”

Optimization of Opto-Electrical and Photocatalytic Properties of SnO2 Thin Films Using Zn2+ and W6+ Dopant Ions

“…The use of dopants to control surface properties of SnO 2 thin films allows obtaining nanostructures with tailored and predictable macroscopic properties [9][10][11], and represents a promising way towards obtaining advanced materials with application in solar energy conversion (photovoltaic, photocatalytic and photoelectrolytic systems) [12][13][14].…”
