UV-Visible analysisZinc oxide nanoparticle size methods? 2024 Elsevier B.V.The study investigates several theoretical and empirical methods for determining the size of zinc oxide nanoparticles (ZnO NPs) and studies their characteristics by using solely UV–visible spectroscopy. The investigation begins ...
Fluence-dependent formation of Zn and ZnO nanoparticles by ion implantation and thermal oxidation: An attempt to control nanoparticle size For possible control of the size of nanoparticles (NPs), the fluence-dependent formation of Zn and ZnO NPs by ion implantation with and without thermal oxi......
The synthesis and characterization of nanosized zinc oxide particles and their application on cotton and polyester/cotton fabrics have been studied for the protection against UV radiation. The nanoparticles are produced in different conditions of temperature (90° or 150°C) and reaction medium (water...
of the intensity of theSurface plasmon resonance(SPR) peak, we can analyze the facts, including increasing size and agglomeration of silvernanoparticles. Previous studies have shown that the spherical silvernanoparticleabsorption spectrum is around 400nm in the UV-visible spectra (Stamplecoskie and ...

The photocurrent (PC) spectra of the as-grown and RTA-treated NWs show a strong peak in the UV region and two other relatively weak peaks in the visible region. The photoresponse measurement shows a bi-exponential growth and bi-exponential decay of the PC from as-grown as well as RTA-...
The optimal dose of ZnO nanoparticles was 1 g L. The average diameter of ZnO was from 52.27 to 304.8 nm. The optimal contact time was chosen for 45 min. After this time, the removal efficiency of arsenic has a slight difference.
This is proven by the additional D-band (1343 cm−1) and G-band (1598 cm−1) that emerge in the Raman spectra for TiO2/rGO samples which are absent in the spectra of TiO2. The G-band is the characteristic peak for sp2 hybridized C–C bonds in graphene. On the other hand, D-...
We also demonstrated Au-ZnO nanocomposite's application to wavelength tunable gas sensor operating at room temperature. The sensing response of Au-ZnO nancomposite is enhanced both in UV and visible region, as compared to control ZnO. The sensitivity is observed to be higher in the visible ...
