Chromium oxide (α-Cr2O3) thin films were prepared using thermal annealing of chromium (Cr)films deposited on quartz substrates by direct current (DC) magnetron sputtering. The annealingprocess of the films was performed for different times of 60, 120,180 and 240 min. The influenceof annealing time on structural, morphological and optical properties of the prepared films wasinvestigated by diffe...

In this study, different samples of Niobium and Vanadium co-doped titania  thin films (5-10-15 mol% Nb and 5-10-15 mol% V) were prepared via sol−gel dip coating method, using niobium chloride as niobium precursor, ammonium metavanadate as vanadium precursor, and titanium (IV) butoxide (TBT) as titanium precursor. The effects of doping amount on the structural, optical, and photo-catalytic prope...

Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophotom...

Two-dimensional (2D) and three-dimensional (3D) magnetic cobalt nanowire thin films with tunable 3-10 nm wire diameters have been electrodeposited using mesoporous silica templates containing 2D hexagonal or 3D cubic pore channels. As compared to bulk cobalt films, the cobalt nanowire thin films exhibit enhanced coercivities and controllable magnetic anisotropy through tuning of the mesostructu...

In this paper, SnO2 and SnS2 thin films were prepared by spray pyrolysis technique on glass substrate. The prepared films were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Aspergillus niger (A. Niger) fungi were grown in an appropriate medium and were exposed to the synthesized SnO2 and SnS2 thin films in a closed glass vessel to measure their nano-biosensing...

Molybdenum oxide (α-MoO)thin films were prepared on quartz and silicon substrates by thermal oxidation of Mo thin films deposited using DC magnetron sputtering method. The influence of thermal oxidation times ranging from 60-240 min on the structural and morphological properties of the preparedfilms was investigated using X-ray diffraction, Atomic force microscopy and Fourier transform infrared...

thin film phthalocyanines(pc), incloding zinc, iron, and magnesium phthalocyani-nes, were prepared by vacuum deposition method. chronocoulometry was used to study the charge transfer reaction mechanism of ionic species through the thin films. the results obtained in chronocoulometric studies shows that the thin film phthalocyanines could operate via two mechanisms.the first mechanism metal pc t...

Zinc oxide thin films have been obtained on bare and GaN buffer layer decorated Si (111) substrates by pulsed laser deposition (PLD), respectively. GaN buffer layer was achieved by a two-step method. The structure, surface morphology, composition, and optical properties of these thin films were investigated by X-ray diffraction, field emission scanning electron microscopy, infrared absorption s...

In this study PbTiO 3 thin films were deposited using metalorganic vapor phase epitaxy (MOVPE). Titanium-isopropoxide and tetraethyl-lead were used as the Ti and Pb precursors, and 0 2 was the oxidizing gas. A wide range of conditions for preparing high quality PbTiO 3 thin film were investigated. The epitaxial PbTiO 3 thin films were grown on (001) SrTiO 3 substrates at a growth temperature of...
