Nanotechnology is related to particles and structures in the range from 1 to 100 nm and thus these are called nanoparticles and nanostructures among other denominations that always have the nano prefix and, hence, we enter the world of nano. One of the materials that have set standards in nanotechnology due to its multiple properties and the most varied nanostructural morphologies is ZnO. Its properties can be modified at convenience, according to its intended application, both by the way it is obtained and by introducing impurities, among others. Among the studies that have been carried out, ZnO doped with transition metals show great potential for use in fields such as optoelectronics, photocatalysis, sensors, spintronics and many others. In the present work a study of the doping efficiency of transition metals, such as Cu, Co and Cr to ZnO nanoparticles obtained by aqueous synthesis. The doping range was up to about 2 at%. The study is supported by elemental, morphological and structural measurements of the nanoparticles.
