Abstract: | Transition metal doped ZnS:Ni and ZnS:Cu and co-doped ZnS:Ni, Mn and ZnS:Cu, Cd nanoparticles were synthesized through the chemical precipitation method in an air atmosphere. The XRD analysis of co-doped samples shows the formation of cubic phase. The average size of nanoparticles ranges from 3.6 to 5.5 nm. The formation of co-doped nanoparticles was confirmed by XRD and PL analysis. The PL spectra show that the obtained nanoparticles have good crystal quality. An optimum concentration of transition metals was selected in co-doped ZnS nanoparticles. |
