2024年6月1日 · Three Samples of ZnO Nanoparticles are synthesized and confirmed by XRD analysis. Bandgap energies, Urbach energies, and Refractive indexes are analyzed by UV–visible absorbance data. Five Size estimation models were employed for size determination. One-way ANOVA variation is observed among the estimation methods.

2017年11月8日 · We found that from the fabricated nanostructures, the NSs photodetector in a thin film form shows a faster rise and decay time both in the UV and visible spectrum region than that of the...

The UV–visible spectrum shows a distinct peak at 363 nm which confirms the creation of ZnO NPs and SEM showed mono-dispersed sphere-shaped NPs. EDX analysis shows the presence of desired ...

2014年5月1日 · This paper reports measurements of the effect of particle size on UV absorption in zinc oxide nanoparticles with sizes in the range of 15–40 nm. It is shown that UV absorption in ZnO nanoparticles exhibits a significant dependence on particle size in particles up to 70 nm.

2019年5月31日 · UV sensors based on the synthesized ZnO NWs/NRs offer great promises for high photo sensitivity with fast response and recovery times. This work presents a synthesis of vertically aligned and uniform ZnO nanowires/nanorods (NWs/NRs) for the fabrication of ultraviolet (UV) photodetectors.

2024年2月14日 · In addition, Cu-doped ZnO and pure ZnO metal–semiconductor-metal photodetector, with Cu as electrode contacts were successfully produced for ultraviolet (UV) detection. The I - V (current–voltage) characteristics were …

In this article, we report on the synthesis, characterization and photocatalytic activity of quasi spherical ZnO nanoparticles obtained by an egg white assisted facile sol–gel type wet method....

In this study, we identified a suitable precursor and good cellular compartmentalization for enhancing bioactive metabolites to produce biosynthetic zinc oxide nanoparticles (ZnO NPs).

2025年1月6日 · Here, we fabricate the ideally surface-passivated colloidal ZnO NCs, which exhibit nearly pure exciton-stemmed UV emission. The nitrogen atoms of amino-moiety of the long-chain oleylamine groups passivate the ZnO NC surfaces and cause complete vanishing of the green emission exhibited in the un-passivated ZnO NCs and usually observed in various ...

2024年5月10日 · The undoped ZnO films exhibited superior optical properties characterized by intense ultraviolet (UV) luminescence, unprecedented ultrafast decay times, and for the case of MF+ECWR-deposited films, suppressed defect-related visible luminescence.
