The effect of different concentrations of urea on the morphology of iron oxide (Fe3O4) magnetic nanoparticles was studied. Fe3O4 magnetic nanoparticles were fabricated by the coprecipitation method. The morphology, crystallinity, compositional purity, and emission characteristics were tested by the techniques of scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and Raman characterization...
60B2O3-30Bi2O3-5TeO2-(5–x)Y2O3-xNd2O3 mole% (0 ≤ × ≤ 4) glasses were prepared by the usual experimental glass-melting procedures. This work was carried out to study the effect of Nd2O3 on the properties of the glasses studied and thereby their structure. The effect of the replacement of Y2O3 by Nd2O3 on the optical and electrical properties of the glass samples was studied. The results obtained showed...
ZnO nanoparticles with hexagonal wurtzite structure were synthesized by using microwave irradiation. The effects of annealing temperatures on the structural, surface morphology and dielectric properties of annealed ZnO nanoparticles were investigated by XRD, FTIR spectra, and dielectric measurements. The XRD reveals the presence of hexagonal wurtzite structure of ZnO average grain size 25.7–36.4 nm...
Annealed ZnO thin film at 400 °C for two hours was deposited on a glass substrate by using pulsed laser deposition (PLD). The structural properties of the annealed ZnO thin film were studied by XRD, TEM and SEM. Gas sensing properties for different gases such as H2 and LPG were investigated. Applying XRD the size of the nanocrystals is found to be 10.61 nm. SEM of the thin film consisted of many grains...
The annealing effects on the structural and optical properties of grown ZnO thin films fabricated by pulsed laser deposition were investigated by using different techniques. The XRD reveals the presence of hexagonal wurtzite structure of ZnO with preferred orientation (002). The average grain size (D) of annealed ZnO nanocrystalline thin films is found to be in the range 7.77–15.91 nm. SEM of the...
