Abstract:In the present work, solution based simple chemical precipitation method has been employed to prepare undoped, cobalt (Co)-doped and cobalt, nickel (Co, Ni) co-doped ZnS quantum dots (QDs). The XRD pattern revealed that all samples displayed cubic zinc blende structure. The average crystallite size of as prepared ZnS QDs were found to be in 1.0 to 1.4 nm range. Surface morphological of synthesized samples were recorded and some distinction in morphological features between undoped, doped and co-doped ZnS QDs w… Show more
