ABSTRACT. In this work, synthesized carbon quantum dots (CQDs) and zinc oxide nanoparticles (ZnO NPs) are used to form ZnO/CQDs nanocomposite. The characterization of nanocomposite using X-ray diffraction (XRD) indicates that ZnO NPs have the same profile, suggesting presence CQDs does not impinge crystal structure in Besides, an analysis performed with scanning electron microscopy (SEM) displa...

In this paper, a semiconducting photonic nanostructure capable of wide range absorption and tunable optical resonance has been designed with a proposed theoretical optimization model. The design consists of ZnO/CdS core-shell nanowire arrays as well as multilayer thin films that act to absorb incident electromagnetic (EM) waves over a broad frequency range. Theoretical, as well as numerical, st...

Nowadays, fabrication of electronic devices using nanostructured materials has been important since it does provide a way of improving devices efficiency. Nanostructured materials have been known to have high surface area per volume and also exhibit unique properties such as visible light transparency and quantum confinement effect. Such characteristics produce excellent reaction area in the de...

PPY, PANI and PPY-PANI-ZnO ternary nanocomposites were synthesized in the laboratory via chemical oxidative polymerization method. The formation of corresponding change nanostructure with incorporation ZnO was examined by X-ray diffraction technique (XRD). Nano-flakes like structure formed PPY-PANI polymeric matrix embodiment nanoparticles, as surface topology images. Optical transmittance spec...

ZnO nano-particles is synthesized using hydrated zinc chloride (ZnCl2.2H2O) as main raw components. It calcined at different temperatures (i.e., 200 ⁰C, 400 ºC, 600 ⁰C and 800 ⁰C). Synthesized characterized by XRD, SEM/EDS, HRTEM, UV Visible, Band Gap. XRD result showed pure wurtzite-structure crystalline nature. Both results SAED obtained from pattern HRTEM studies are indicated similar inform...

Zinc oxide (ZnO) nanostructure was successfully synthesized on an alumina substrate by the hydrothermal method. The method consists of two stages: preparation seeding layers and growth ZnO nanostructures. 0.4 M Acetate Dihydrate (Zn(CH3COO)2·2H2O) 3 Sodium Hydroxide (NaOH) were used as precursors. process carried out at 90 °C for 4 hours. Morphological characterization nanostructures conducted ...
