Notes:
Diluted magnetic semiconductors (DMS), which have both semiconducting and magneticproperties, are those in which transitions metal ions substitute cations of host semiconductormaterials [1]. There is a great interest for DMS for use as the material of spintronics. In this study isreported the structural and morphologic characterization of Zn1.95Co0.05O nanoparticles obtained byPechini method and combustion reaction. The powders resulting were characterized by X-raydiffraction (XRD) for determination of the phases, crystalline phase and lattice parameter; nitrogenadsorption by BET for determination of the specific superficial area and calculation the particle sizefrom the superficial area and scanning electron microscopy (SEM) for morphologic analysis. TheXRD results demonstrated the viability of obtaining crystalline and nanosize powders by the bothsynthesis routes. For all samples the average crystallite sizes was nanosized, but the powdersobtained by reaction combustion is smaller. The SEM micrographs shows that the powders obtainedfor both syntheses are constituted of soft agglomerates
