In the present work, zinc oxide has been synthesized by evaporation, condensation and oxidation of Znmetallic at atmospheric pressure in a quartz tubular reactor at temperatures between 900 °C and 1100 °C, with an end that allows the injection of argon and oxygen to achieve pure undoped ZnO crystals, and to determine their influence on the morphological and luminescent characteristics of the synthesized particles. A predominance of tetrapod-like morphologies with pyramidal arms and dimensions from a few hundred nanometers to several microns has been found. The synthesized particles were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and their optical properties were analyzed by cathodoluminescence (CL) and photoluminescence (PL). The monochromatic images acquired by cathodoluminescence show which region of the particles is responsible for the emission peaks, which allows focusing the study on the emission of interest.
