Abstract:
The process of doping of CdS nanoparticles with Mn during colloidal synthesis is analyzed by EPR and optical
studies. Analysis of EPR results demonstrated that Mn2+ ions are successfully incorporated into the nanoparticles
and occupy the crystal sites both in the bulk of a NP and near the surface of a NP. Optical absorption
measurements revealed the retardation of absorption edge shift during the growth for Mn-doped CdS NPs as
compared to the undoped CdS NPs. It was concluded that the presence of Mn in the solution leads to the
inhibition of NPs growth.
