Nanostructured semiconductor materials are considered potential candidates for the degradation of textile wastewater via photocatalytic process. This study aims to produce hexagonal gallium nitride (GaN) nanoplates and zinc oxide (ZnO) nanoparticles in a deionized water environment utilizing one-step arc discharge Detailed characterization samples has been completed scanning electron microscope...

In this study, ZnO/ZnAl 2 O 4 /Zn TiO composite nanostructured thin films are deposited assisted with hollow-cathode glow discharge (HCD). The using various argon-oxygen gases mixture (0–50% ), and its effect on film quality, optical electrical properties is examined. Remarkably, instead of metallic targets, ZnO, 2, Al 3 powders filled in used for deposition, thus no specific targets required t...

Chemoresistors working at room temperature are attractive for low-consumption integrated sensors. Previous studies show that this feature can be obtained with photoconductive porphyrins-coated ZnO nanostructures. Furthermore, variations of the porphyrin molecular structure alter both the chemical sensitivity and the photoconductivity, and can be used to define the sensor characteristics. Based ...

In order to synthesise hierarchical zinc oxide (ZnO) nanomaterials with a high surface-to-volume ratio, well-controlled multistage hydrothermal method was developed. Hierarchical ZnO nanobrushes (ZNBs) built from initial mono-morphological nanomaterials, nanowires (ZNWs), and nanoplates (ZNPs) were developed using sequential nucleation growth following process. which are comprised of one-dimens...

We report on hybrid films based on ZnO/organic dye prepared by electrodeposition using tetrasulfonated copper phthalocyanines (TS-CuPc) and Eosin-Y (EoY). Both the morphology and porosity of hybrid ZnO films are highly dependent on the type of dyes used in the synthesis. High photosensitivity was observed for ZnO/EoY films, while a very weak photoresponse was obtained for ZnO/TS-CuPc films. Des...

The phenomenon of persistent photoconductivity is elusive and has not been addressed to an extent to attract attention both in micro and nanoscale devices due to unavailability of clear material systems and device configurations capable of providing comprehensive information. In this work, we have employed a nanostructured (nanowire diameter 30-65 nm and 5 μm in length) ZnO-based metal-semicond...

This work presents a novel technique to deposit ZnO thin films through a metal vacuum evaporation technique using colloidal nanoparticles (average size of 30 nm), which were synthesized by our research group, as source. These thin films had a thickness between 45 and 123 nm as measured by profilometry. XRD patterns of the deposited thin films were obtained. According to the HRSEM micrographs wo...
