Resumen: En el presente trabajo se ha sintetizado oxido de zinc por evaporacion, condensacion y oxidacion de Znmetalico a presion atmosferica en un reactor tubular de cuarzo a temperaturas entre 900 °C y 1100 °C, con unextremo que permita la inyeccion de argon y oxigeno para lograr cristales puros no dopados de ZnO, y paradeterminar su influencia en las caracteristicas morfologicas y luminiscentes de las particulas sintetizadas. Se haencontrado predominancia de morfologias tipo tetrapodos con brazos piramidales y de dimensiones de pocascentenas de nanometros hasta varias micras. Las particulas sintetizadas se caracterizaron mediante difraccion derayos X (DRX), Microscopia Electronica de Barrido (MEB), Microscopia Electronica de Transmision (MET), y suspropiedades opticas se analizaron por catodoluminiscencia (CL) y fotoluminiscencia (PL). Las imagenesmonocromaticas adquiridas por catodoluminisciencia logran mostrar cual region de las particulas es responsable delos picos de emision, lo que permite focalizar el estudio en la emision de interes. Abstract: Zinc oxide is synthesized by evaporation, condensation and oxidation of Zn metal at atmosphericpressure in a quartz tubular reactor at temperatures between 900 °C and 1100 °C with one end that allows theinjection of argon and oxygen to achieve pure crystals undoped ZnO and determine the influence on themorphological and luminescent characteristics of the synthesized particles. It has been found predominance oftetrapod type with pyramidal morphologies and dimensions arms few hundred nanometers to several microns. Thesynthesized particles have been characterized by X ray diffraction (XRD), scanning electronic microscopy (SEM),transmission electronic microscopy (TEM) and its optical properties have been analyzed by cathodoluminescence(CL) and photoluminescence (PL). Monochrome images acquired by catodoluminiscence region may show whatparticles region are responsible for the emission peaks, allowing the study to focus on the issue of interest.
