Characterization of ZnO flowers of hexagonal prisms with planar and hexagonal pyramid tips grown on Zn substrates by a hydrothermal process

Flower-like ZnO crystals on zinc substrates were synthesized by a simple hydrothermal method in different solutions containing 0.05, 0.10, 0.20, 0.30 and 0.40 g LiOH. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron mi...
