Preparation of Cu2O Films with Preferred Crystal Orientations by Electrodeposition Method

Microstructure and optical properties of nanocrystalline Cu2O thin films prepared by electrodeposition

Cuprous oxide (Cu2O) thin films were prepared by using electrodeposition technique at different applied potentials (-0.1, -0.3, -0.5, -0.7, and -0.9 V) and were annealed in vacuum at a temperature of 100°C for 1 h. Microstructure and optical properties of these films have been investigated by X-ray diffractometer (XRD), field-emission scanning electron microscope (SEM), UV-visible (vis) spectro...

Preparation of Gd2O3 Ultrafine Nanoparticles by Pulse Electrodeposition Followed by Heat-treatment Method

Gd2O3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. First, Gd(OH)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (PC) mode. The deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. The electrodeposited precursor was the...

Preparation of SOFC Anodes by Electrodeposition

Anodes for solid oxide fuel cells (SOFCs) have been prepared by electrodeposition of either Co or Ni into a layer of porous yttria-stabilized zirconia (YSZ), 60 μm thick. The YSZ, having 65% porosity, was prepared by tape casting with graphite pore formers and was attached to the dense YSZ electrolyte. After adding 10 vol % CeO2 by impregnation of aqueous solutions of CeNO3)3, followed by calci...

Structural properties of Cu2O epitaxial films grown on c-axis single crystal ZnO by magnetron sputtering

Preparation of crystalline zinc oxide films by one-step electrodeposition in Reline

One-step electrodeposition of crystalline zinc oxide thin films on Molybdenum/glass substrates in a low-cost ionic liquid, Reline composed of urea and choline chloride, is presented. X-ray diffraction spectroscopy shows the thin films have wurtzite structure. Raman microspectroscopy indicates a slight oxygen deficit in the film. Both X-ray energy dispersion and X-ray photonelectron spectroscopy...
