Investigation of Synthesized ZnO Nanoparticles
Author(s): Åžeyda Çolak and Cangül Aktürk
In the present study, undoped ZnO and Mn, Cu and Co doped (5 mol%) ZnO nanoparticles have been synthesized by hydrosis method and structural, optical, magnetic properties of these samples have been performed. Crystal sizes of the undoped and doped ZnO nanoparticles have been determined to be ∼12 nm by XRD analysis. The crystallite size of ZnO nanoparticles have been observed to be decreased by doping process. A single, broad and unresolved EPR signal with additional two resonance peaks, Ia and Ib which are believed to be related with oxygen and zinc damage centers, and have been arised for the undoped ZnO nanoparticles. Six resolved, four resolved and a single unresolved EPR resonance signals were also recorded for the Mn, Cu and Co doped ZnO nanoparticles, respectively. UV irradiat... view more»
