ZnO nanoparticles were synthesized by spray pyrolysis method using the zinc acetate dihydrate as starting material at various synthesis temperatures. The structures of the synthesized ZnO were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transformation infrared (FT-IR), and UV-vis spectroscopy. With increasing synthesis temperature, the mean diameter of...
The effect of deposition temperature on the electrical, optical, structural, and morphological properties of indium doped zinc oxide thin films, ZnO:In, deposited by the chemical spray technique have been studied in this work. The starting solution was prepared using zinc pentanedionate and indium chloride as Zn and In precursors, respectively. Ethyl alcohol was utilized as solvent. The films were...
In this study, zinc oxide (ZnO) and aluminium doped zinc oxide (ZnO:Al) thin films were deposited by reactive chemical pulverization spray pyrolysis technique on heated glass substrates at 450degC. X-ray diffraction (XRD), scanning electron microscopy (SEM) and third harmonic generation (THG) are used to characterize their structure , morphology and nonlinear optical properties as a function of Al...
ZnO nanorods were successfully synthesized by thermal decomposition of Zn (OH)2 in the ionic liquid 1-butyl-3-ethylimidazolium tetrafluoroborate. Their structure and morphology were characterized by means of infrared spectroscopy (IR), X-ray powder diffraction (XRD), and transmission electron microscopy (TEM). The TEM results indicate that the diameter of the ZnO nanorods was 10 nm, and the length...
ZnO nanoparticles were synthesized by flame spray pyrolysis (FSP) using zinc naphthenate as a precursor dissolved in toluene/acetonitrile (80/20 vol%). The particle properties were analyzed by XRD, BET, and HR-TEM. The sensing films were produced by mixing the particles into an organic paste composed of terpineol and ethyl cellulose as the vehicle binder and were fabricated by doctor-blade technique...
ZnO nanoparticles were produced by FSP using zinc naphthenate as a precursor dissolved in toluene/acetonitrile (80/20 vol%). The phase and crystallite size were analyzed by X-ray diffraction (XRD), and the specific surface area (SSA) of the nanoparticles was measured by nitrogen adsorption (BET analysis). The ZnO particle size and morphologies was further investigated by transmission electron microscopy...
The structural, optical and electrical properties of ZnO:ln thin films prepared by spray pyrolysis method are examined. The used spray solution (0.2 M) was prepared by adding indium chloride InCl/sub 3/ to the precursor of zinc acetate dissolved in mixed solution 80% H/sub 2/O: 20%CH/sub 3/OH. The XRD patterns for incorporated ZnO film with different concentration of indium shows three additional...
