Resumen
This paper discusses the preparation and characterization of Zn 0.95Mn0.05O phase obtained by the polymeric precursor method for DMS applications. The as-obtained powders were calcined between 500 to 800°C and characterized by XRD, SEM and BET. The XRD analysis of the powder showed a crystalline material containing second phase. The crystallite sizes ranged from 20 to 51 nm. The micrographs showed that the powders consisted of soft and homogeneous agglomerations. The nitrogen adsorption/desorption curves of the Zn0.95Mn0.05O phases were type II curves, which is characteristic of mesoporous materials.
