Highly arranged porous anodic titania (TiO 2 ) nanotube arrays (ATNT) were fruitfully fabricated by the anodization of Ti foil in an ammonium fluoride electrolyte.
In this work, a method of enhancing the electrical properties electrodeposited p-type Cu2O film is described. Sodium doped was achieved by adding sodium aluminate complex solution to electrodeposition alkaline Cu (II) lactate electrolyte. The optimal Na content [Na at% atomic ratio] incorporated in found be approximately 1.34 at.%. XPS result shows that binding energy at 1072.4 ± 0.2 eV corresponds presence oxide. optimized resistivity and hole concentration were 291 Ω cm 2.13 × 1018 cm3,...
Abstract The optical diffuse reflectance data of a semiconductor material is usually converted into the Kubelka–Munk function before proceeding to process conventional Tauc’s plot from which bandgap energy can be determined. Firstly, it conventional/ customary convert percentage ( R ∞ (%)) obtained UV-vis measurement an equivalent ) that range between 0 and 1 processing plot. Secondly, multiplied by incident photon energy, hv , produce all-elements/ comprehensive Literature scarce...
Fast with high-performance CuO nanorod arrays IR photodetector was fabricated using arrays/AAO assembly. The based on MSM Al contact electrodes and its optoelectronic properties were examined. used in the experiment synthesized by DC electrodeposition method into Si-based/AAO template. electrical performance photoelectric response studied, results showed that exhibited a high sensitivity to 808 nm infrared diode laser source. Both recovery time found be fast; 0.19 0.15 s, respectively, which...
Zinc sulfide (ZnS) thin films have been successfully deposited via spray pyrolysis using an aqueous solution of thiourea and zinc acetate onto glass substrate. The effect varying substrate temperature (150, 200,250 300 °C) on structure optical properties is presented. characterized by X- ray diffraction (XRD), UV-Vis-NIR spectrometry, photoluminescence (PL) spectroscopy field emission scanning electron microscopy (FESEM). All the ZnS exhibit a cubic structure, while crystallinity morphology...
The presence of multiple phases/ components within a nanocomposite material impacts the properties nanomaterial. Therefore, there is need to estimate phase fraction each component present in sample. Spurr-Myers proposed valuable formula for estimating rutile and anatase TiO2 sample from X-ray diffraction. However, this dedicated inapplicable samples that contains more than two phases. research work simple method quantifying all types nanomaterials consist or Precision/ accuracy test carried...
