Zinc oxide nanoparticles (ZnO-NPs) were synthesized via a solvothermal method in triethanolamine (TEA) media. TEA was utilized as a polymer agent to terminate the growth of ZnO-NPs. The ZnO-NPs were characterized by a number of techniques, including X-ray diffraction analysis, transition electron microscopy, and field emission electron microscopy. The ZnO-NPs prepared by the solvothermal proces...

Semiconductor nanocrystals (NCs) have emerged as an important class of materials because of their tunable optoelectronic properties that arise from quantum size effects. They can be used as active components in functional nanocomposites, chemical sensors, biomedicine, optoelectronics, and nanoelectronics. More recently, NCs of different shapes, including rods, bipods, tripods, tetrapods, and cu...

In this study, four types of standardized ZnO nanoparticles were prepared for assessment of their potential biological risk. Powder-phased ZnO nanoparticles with different particle sizes (20 nm and 100 nm) were coated with citrate or L-serine to induce a negative or positive surface charge, respectively. The four types of coated ZnO nanoparticles were subjected to physicochemical evaluation acc...

The use of plant extract in the synthesis of nanostructured materials can be a cost effective and eco-friendly approach. In this paper we report the biosynthesis of zinc oxide nanoparticles using Citrus aurantifolia extracts. Spherical zinc oxide nanoparticles were produced using different concentration of zinc acetate which was used as the zinc source. FESEM imaging showed the formation of nan...

The synthesis of semiconductor nanoparticles is an expanding research area due to the potential applications in the development of nanotechnologies. Especially, biosynthesized nanoparticles have become an important branch of nanotechnology. In the present work, we describe a low-cost and simple procedure for biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using Pyrus Pyrifolia leaf extract. ...

This work contributes to the discussion on influence of back contact electrical properties Cu2ZnSnS4 (CZTS)-based solar cells. Devices with noble metals (Au, Ag and Pt) such as FTO/ZnS/CZTS/Au, FTO/ZnS/CZTS/Pt FTO/ZnS/CZTS/Ag were investigated by means current voltage characteristic in dark (FTO = fluorine-doped tin oxide). The originality this is that all active layers (absorbing buffer layers...

Cu2SnS3 (CTS) nanorods were synthesized with a controllable aspect ratio via a facile phosphine-free colloidal synthesis. This synthesis can be readily extended to obtain Cu2ZnSnS4 (CZTS) nanorods with tunable Zn content.

Cu(2)ZnSnS(4) (CZTS) nanocrystals sterically stabilized with oleic acid and oleylamine ligands and dispersed in nonpolar organic liquids have been extracted into, and electrostatically stabilized in, polar liquids by covering their surfaces with S(2-).

Doping impurity into ZnO is an effective and powerful technique to tailor structures enhance its optical properties. In this work, Zn1−xMgxO Zn1−x−yMgxByO nanoparticles (x = 0, 0.1, 0.2, 0.3, 0.4; y 0.02, 0.04) were synthesized via one-pot method. It shows that the Mg B dopants has great influence on crystallinity surface morphology of nanoparticles, without changing wurtzite structure ZnO. The...
