Hexagonal ZnO nanocolumns (NC´s) were synthesized by chemical bath
deposition (CBD) on previously ZnO nanoseeds deposited on corning glass with
substrate temperature from 300 to 550 °C in steps of 50 °C by spray pyrolysis
technique. Before spray pyrolysis process, the nanoseeds were dissolved in
water and dispersed with ultrasound. Morphological study was carried out by
Scanning Electron Microscope (SEM); hexagonal ZnO nanocolumns were
observed, the lowest diameters were obtained at substrate temperature
between 400 and 450 °C (seeds deposition). The best vertical alignment was
observed on nanocolumns grown over ultrasound-dispersed nanoseeds.
Raman spectroscopy was used to evaluate the vibrational modes, crystal quality
and the verticality of the ZnO nanocolumns. A relationship between the shift of
E2H mode, the deposition temperature ZnO seeds and the nanocolumns
diameters was found.
