Synthesis and Characterization of Zn-doped CuWO4Nanoparticles and Their Opto-structural Properties
Abstract: CuWO4 and Zn-doped CuWO4 nanoparticles were prepared by a solid-state reaction method. The XRD study confirms the triclinic crystal structure for both samples and the peak shift is noticed for Zn-doped CuWO4 particles with high crystallinity. The FTIR spectra show metal oxide vibration which arose from the CuWO4 and Zn-doped CuWO4 particles. The optical absorption spectra exhibit strong absorption in the visible region and the band gap of Zn-doped CuWO4 is found to be increased to 2.44 eV compared to that of CuWO4 (2.36 eV), which is due to the elevated conduction band levels after Zn-doping. The SEM images of both CuWO4 and Zn-doped CuWO4 nanoparticles show densely aggregated particles.
Keywords: Copper tungstate, Zn-doped CuWO4, Absorption, Nanoparticles.
