A simple fabrication method of silver (Ag) nanoislands on ZnO films is presented. Continuous wave and time-resolved photoluminescence and transmission are employed to investigate modifications of visible and UV emissions of ZnO brought about by coupling to localized surface plasmons residing on Ag nanoislands. The size of the nanoislands, determining their absorption and scattering efficiencies...

We report the influence of zinc oxide (ZnO) seed layers on the performance of ZnO-based memristive devices fabricated using an electrodeposition approach. The memristive element is based on a sandwich structure using Ag and Pt electrodes. The ZnO seed layer is employed to tune the morphology of the electrodeposited ZnO films in order to increase the grain boundary density as well as construct h...

This study focuses on the fabrication and characterization of nanostructured zinc oxide films deposited glass substrates using sol–gel dip-coating methods. The thin are functionalized with silver ions at various Ag+ concentrations (10−2, 10−3, 10−4 M) through room temperature ion fixation process without ultraviolet (UV) illumination. Physicochemical techniques, such as employing Scanning Elect...

In this research work, the production of undoped and silver (Ag) doped zinc oxide (ZnO) thin films for food packaging applications was developed. The main goal was to determine the influence of coatings morphology and thickness on the antimicrobial performance of the produced samples. The ZnO based thin films were deposited on PET (Polyethylene terephthalate) by means of DC reactive magnetron s...

(GaN)1-x(ZnO)x solid solution has attracted extensive attention due to its feasible band-gap tunability and excellent photocatalytic performance in overall water splitting. However, its potential application in the photodegradation of organic pollutants and environmental processing has rarely been reported. In this study, we developed a rapid synthesis process to fabricate porous (GaN)1-x(ZnO)x...

Optimization of thin film photovoltaics (PV) relies on characterizing the optoelectronic and structural properties of each layer and correlating these properties with device performance. Growth evolution diagrams have been used to guide production of materials with good optoelectronic properties in the full hydrogenated amorphous silicon (a-Si:H) PV device configuration. The nucleation and evol...

Abstract Heterogeneous photocatalysts have been widely used for the removal of various organic pollutants from wastewater. The main challenge so far resides in sustainability process, with regard to synthesis and application under visible light. In this study precipitated materials Moringa oleifera seed (MO), groundnut shells (GS) apatite (A) agrowastes were functionalized zinc oxide (ZnO) silv...

Herein, we reported a simple and "green" method for preparing the ternary photocatalyst Ag-graphene quantum dots (GQDs)-ZnO. In this method, an aqueous solution of GQDs not only acted as a substituent for the organic solvent for preparing the ZnO precursor but was also used as a reducing agent for the in situ synthesis of Ag nanoparticles (NPs). X-ray diffraction analysis and scanning electron ...
