Structural and optoelectronic properties of antimony incorporated tin oxide thin films

Sensing properties of sprayed antimony doped tin oxide thin films: Solution molarity

“…The materials will provide more surface sites available for oxygen to be adsorbed on them and to make contact with the surrounding gases [4]. The synthesis of ATO is of great technological and scientific interests owing to the use of these materials as transparent electrodes, heat mirrors, displays, electrochromic windows, catalysts, rechargeable Li batteries, and energy storage devices and has potential uses in photovoltaic and optoelectronic devices [5,6]. Other interesting features of ATO are their gas sensing properties.…”

Comprehensive optimization of electrical and optical properties for ATO films prepared by pulsed laser deposition

“…A R Babar et al [13] prepared ATO film with a "figure of merit" of 2.11×10 -3 Ω -1 by spray pyrolysis technique. It provides a confirmed accordance to evaluate the TCO materials, making the ATO thin films suitable for the application of transparent conductive electrode in solar cells.…”

“…Various deposition methods have been used to prepare the ATO thin films, such as sol-gel dipcoating technique [9][10][11] , spray pyrolysis technique [12][13][14] and magnetron sputtering technique [6][7] . The structural, electrical and optical properties of ATO thin films dependent on the fabrication parameters, such as deposition temperature, oxygen pressure, thickness, annealing treatment and Sb content, have been intensively investigated.…”

“…A R Babar et al [13][14] discovered that as Sb content was increased, the polyhedron like grains of ATO thin films were reduced and converted into twisted large round grains, meanwhile, the electrical and optical properties were improved with the increase of Sb content to 2 at% and then degraded when the Sb content was greater than 2 at%. L K Dua et al [15] found that with the increase of Sb content, Burstein-Moss shift was observed in both direct and indirect band gaps and the optimal electrical and optical properties were obtained with a Sb content of 30 at%.…”

Gas Sensing Characteristics of Sb-doped SnO2Nanofibers

“…6c). Babar et al [16] prepared Sb-doped SnO 2 thin films by spray pyrolysis of the solution containing SnCl 4 and SbCl 3 at 475 C and observed that the resistivity of the thin film was decreased as the Sb doping concentration was increased. The XPS analysis results confirmed the dominance of Sb 5+ over Sb 3+ and attributed the decrease of resistivity to the increase of electron concentration by the incorporation of Sb 5+ ions into Sn 4+ sites.…”
