A sol-gel dip-coating process was used to deposit almost stress-free highly c -axis oriented zinc oxide (ZnO) thin films onto glass substrates. The effects of low silver doping concentration (Ag/Zn < 1%) on the structural, morphological, optical, and waveguide properties such were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy, UV-Visible spectrophotometry, M-lines spectroscopy (MLS). XRD analysis revealed that all in single phase had...
Abstract This research investigates the deposition of ZnO thin films on glass substrates at ambient temperature using radio-frequency (RF) magnetron sputtering, with RF power levels between 50 and 300 W. The were subsequently annealed in air 300°C for 60 minutes. Characterization focused how annealing affect their microstructure, morphology, optoelectronic properties. X-ray diffraction analysis revealed that all crystallized hexagonal wurtzite phase, increased leading to stronger (002) peak...
Abstract Pure ZnO and Ce-doped (5 at.%) aerogels were prepared by dissociation of dihydrate zinc acetate cerium nitrate in methanol, followed drying supercritical conditions the solvent. The concentration solution atomic ratio Ce/Zn fixed at 0.2 mol/L 0.05 mol/L, respectively. XRD results showed a hexagonal wurtzite structure aerogel crystallites formation separate second phase ceria cubic with fluorite 7.4 nm size. introduction had negative effect on crystalline quality. size was found to...
