The synthesis of CdTe/ZnS core/shell quantum dots using molecular single-source precursors

Whilst single-source precursors have emerged as an effective method of preparing semiconductor quantum dots, few single-source precursors have been employed for cadmium telluride quantum dots despite the materials exhibiting a wide range of size quantisation effects. In this paper, we explore the use Cd(TePh)2 with amine solvents and capping agents to yield CdTe particles, and also report on the use of a common zinc dithiocarbamate to prepare a ZnS shell, making the synthetic procedure based entirely on single molecular precursors.
