Nanocrystalline ZnO powders have been synthesized by a low temperature solution combustion method. The photoluminescence (PL) spectrum of as-formed and heat treated ZnO shows strong violet (402, 421, 437, 485nm) and weak green (520nm) emission peaks respectively. The PL intensities of defect related emission bands decrease with calcinations temperature indicating the decrease of Zn i and V...
Spherical shaped ZnO nanopowders (14–50nm) were synthesized by a low temperature solution combustion method in a short time <5min. Rietveld analysis show that ZnO has hexagonal wurtzite structure with lattice constants a=3.2511(1)Å, c=5.2076(2)Å, unit cell volume (V)=47.66(5) (Å) 3 and belongs to space group P63mc. SEM micrographs reveal that the particles are spherical in shape and the...
Cu (0.1mol%) doped ZnO nanopowders have been successfully synthesized by a wet chemical method at a relatively low temperature (300°C). Powder X-ray diffraction (PXRD) analysis, scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transformed infrared (FTIR) spectroscopy, UV–Visible spectroscopy, Photoluminescence (PL) and Electron Paramagnetic Resonance (EPR) measurements...
