Resumen:

An experimental study of the crystallization process of Cu2O samples from polycrystalline copper plates is presented. The crystallization process consists of two stages: In the first stage polycrystalline copper plates were wholly oxidized at 1020°C in air, in the second stage the Cu 2O samples were crystallized through an annealing process at temperatures in the range of 1040-1070°C, by several hours to promote the increase in size of the crystallites constituting the initial Cu2O sample. The Cu2O samples were characterized by X-ray diffraction and photoluminescence measurements. With the processing conditions used in the annealing process, Cu2O samples with single crystalline areas of more than 2 mm in diameter are observed. On the basis of the experimental results, a model for the crystallization of Cu2O is presented. © 2007 IEEE.
