摘要：
A facile approach to the synthesis of hafnium oxide nanoparticles (HfO2 NPs) using the precipitation method has been reported. The X-ray diffraction (XRD) pattern of the HfO2 NPs revealed the monoclinic structure, which was also supported by FTIR spectra. From the XRD pattern, the average crystallite size was calculated as 24 nm using the Scherrer formula. The field emission scanning electron microscope (FE-SEM) image showed that the synthesized HfO2 NPs were spherical in shape with an average particle size of about 25 nm, which was found to be very close to the XRD results. The optical band gap (E-g) of the HfO2 NPs was calculated as 6.09 eV. (C) 2012 Elsevier B.V. All rights reserved.
