Abstract
Uniform zinc oxide (ZnO) hexagonal microprisms were synthesized as thin films on aluminum substrates using the spray pyrolysis technique at a substrate temperature of 350 ± 5 °C. The films were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray energy dispersion spectroscopy (EDS). X-ray diffraction revealed that the prisms are highly (002) oriented, and SEM images revealed that the prisms are perpendicular to the substrates. EDS report showed that the films are oxygen rich and they contain chlorine and sulfur. The prisms showed hexagonal cross sections with apparent crystallographic facets and pyramidal tips. ImageJ software was used to estimate the diameter of the prisms, their surface area, solidity, and circularity. The average diameter was found to be 322 ± 109 nm, and the average surface area was found to be 3.3 × 105 ± 3.7 × 104 nm2. Circularity, which is a measure of compactness, was found to be 0.91 ± 0.01. These prisms are of potential use in solar cells and optoelectronic devices.
