Abstract: Nb2O5 nanoparticles have been successfully synthesized via a hydrothermal process. In the reaction process, the commercial Nb2O5 powder, H2O2 and NH3 aqueous solutions have been used as precursors. The crystallographic phases, optical and vibronic properties were examined by X-ray diffraction (XRD) and FT-IR spectroscopic methods. Morphology of the produced samples was studied using a scanning electron microscope (SEM). From the X-ray diffraction patterns, it suggested that the product was well crystallized and had the crystal structure oforthorhombic phase of Nb2O5.The average crystallite sizes of nanoparticles were calculated by applying the Debye-Scherrer......
