Effect of Capping Agent on Structural and Optical Properties of Niobium (V) Oxide Nanoparticles Synthesized by Thermolysis Method

We provide here structural features and the optical properties of Niobium (V) Oxide nanoparticles (NPs) synthesized by thermolysis method. It A quick and affordable technique to produce NPs has been found, 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. The average crystallite size of nanoparticles calculated from XRD analysis was observed to be 18–30[Formula: see text]nm. Measurements of diffuse reflectance spectroscopy in the ultraviolet-visible region indicate that the optical band gap values (∼3.10[Formula: see text]eV, 3.11[Formula: see text]eV, 3.13[Formula: see text]eV, and 3.14[Formula: see text]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 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. The work identifies the characteristics of Niobium (V) Oxide nanoparticles that make the material adaptable, enabling its use in high-power batteries, sensors, and supercapacitors. PVP’s effectiveness as a capping agent for nanoparticle formation is also described.
