Influence of transition metal (Cu, Al) ions doping on structural and optical properties of ZnO nanopowders
Author(s): V Sreeram
Abstract: Al doped ZnO, Cu doped ZnO Nanoparticles were successfully synthesized by Sol-Gel Method and Zinc Chloride(ZnCl2),Potassium Hydroxide( KOH), Aluminum Nitrate(Al(NO3)2, Copper Nitrate (Cu(NO3)2) and Ethanol(C2H6O) were used as a precursors. The structural and optical properties of Nanoparticles were analyzed by means of XRD (X-Ray Diffraction), SEM (Scanning Electron Microscopy) and FTIR (Fourier Transform Infra-Red spectroscopy). The results of Cu doped ZnO and Al-doped ZnO nanoparticles were also compared to investigate the structural and optical properties. XRD analysis reveals that both the samples crystallizes in hexagonal wurtzite structure and exhibit no impurity phase. The crystalline size of 28.43 nm and 6.87 nm are obtained in Cu doped ZnO and Al doped ZnO Nanoparticles. Therefore, the decrease in the crystalline size can be seen with the change in doping element. The optical properties also depend on the type of doping due to the Al-N bond intensity, The Al doped ZnO powder is stronger than Cu doped ZnO.
