Composite microstructures of zinc oxide (ZnO) and nickel oxide (NiO) were
obtained by hot filament chemical vapor deposition (HFCVD) technique having
used a ZnO and NiO tablet as a solid source. The tablet was fabricated with a
ratio (1:1). The composites were deposited at different temperatures on (101)
silicon substrates. The surface morphology of these microstructures has been
observed by scanning electron microscopy (SEM). The effect of varying the
temperature deposition has been analyzed by photoluminescence (PL), x-ray
diffraction (XRD) and Raman techniques. PL shows the typical ZnO spectrum
with a high emission in the visible range that were attributed to the
incorporation of nickel atoms inside the crystal lattice (wurtzite type) of zinc
oxide. This effect is observed in the shifts of the XRD peaks. With Raman
characterization was possible to find the vibrational modes of ZnO and NiO. By
SEM it was observe different morphological growths as microspheres and
clusters.
