Synthesis and characterization of ZnS:Co nanoparticles prepared through wet chemical method

초록

Homogeneous ZnS-Co-doped nanoparticles (ZnS:Co) were accomplished through wet chemical method with the aid of a buffer solution at room temperature. Based on theoretical calculations, the pH of the reaction and the type of buffer solution were determined. The results of X-ray diffraction analysis showed that the change of lattice constant in ZnS:Co can be detected with a change of Co concentration. The average size of ZnS nanocrystallites, estimated by the Debye-Sherrer formula, was about 3 nm. Also, optical and magnetic properties were tested with the ZnS:Co nanoparticles in various Co concentrations. © 2013 Taylor & Francis.
