Demonstrates how varying capping agents affect structural and optical properties in niobium oxide nanoparticles, suggesting implications for nanotechnology applications.
We provide here structural features and the optical properties of Niobium (V) Oxide nanoparticles (NPs) synthesized by thermolysis method. It is found a quick and affordable technique to produce nanoparticles (NPs), and it was utilized to create Niobium (V) Oxide NPs using a set amount of precursor Niobium pentachloride and a variable amount of surfactant Polyvinylpyrrolidone (PVP). Utilizing X-ray diffraction (XRD), Field Emission Scanning Electron microscopy (FESEM), Fourier Transform Infrared Spectroscopy (FT-IR), and Ultraviolet-Visible (UV-Vis) spectroscopic techniques and Raman Spectroscopy, NPs were thoroughly studied. XRD and Raman Spectroscopy were employed to verify the crystalline quality and stoichiometry of these nanoparticles. Approximately 18 - 30 nm was the size obtained by applying the Scherrer method to determine crystallite sizes. Measurements of diffuse reflectance spectroscopy in the ultraviolet-visible region indicate that the optical band gap values (~3.10, 3.11, 3.13, and 3.14 eV) varied during the crystal formation process. The orthorhombic phase of the material is shown by the Raman vibrational modes. The material's vibrational information is collected by Fourier transform infrared spectroscopy (FT-IR), which identifies the various modes of stretching vibration of oxygen and niobium in the spectrum. It was found that all samples exhibited the fingerprint stretching vibrations within a particular range.
