2 sty 2019 · UV–Vis–NIR absorption spectra were recorded to investigate the optical properties of the TiO 2 and TiN NPs prepared at different temperatures. Figure 4 displays a characteristic spectrum of TiO 2 NPs with the fundamental absorbance stopping edge at ~ 400 nm.
11 maj 2024 · The synthesized tin oxide nanoparticles were analyzed using characterization techniques like UV–visible spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), EDX, and...
The light sensitivity of a novel TiO2/TiN-nanotubes-based photodetector is improved by coating it with Au nanoparticles. Using a porous aluminum oxide template (PAOT), TiO2/TiN...
In this work we have developed a colorimetric sensor array for defining the physicochemical properties of NPs in aqueous solution with ultra-low concentrations (e.g. 10 −7 g ml −1 for gold NPs).
28 maj 2021 · Some of the techniques used for characterizing green synthesized SnO 2 NPs are UV–Vis, FTIR, XRD, EDS, SEM, and TEM. UV–Vis spectroscopy is used to monitor nanoparticle formation by studying their optical properties.
In this paper, titanium nitride nanoparticles were prepared in three methods; in the first method, titanium nitride nanoparticles were prepared by the ball milling method; in the second and...
UV-VIS transmission spectrum of the irradiated sample shows a well-defined dip at 635 nm, associated with surface plasmon resonance. Using various solvents, we demonstrate that the position of the dip is sensitive to the solvent, which presents interest for biosensing applications using TiN nanoparticles.
