Paper Abstract

A two-step high temperature colloidal doping technique has been used to synthesis Co-Ni co-doped CdS/ZnS core/shell nanocrystals in organic phase. Co-Ni ions were incorporated into the CdS quantum dots core pursued by ZnS shell (six monolayers) which was developed on top of it. The co-doped nanocrystals were further characterized usingtransmission electron microscopy (TEM),X-ray diffraction (XRD), ultraviolet-visible (UV-VIS) spectroscopy and photoluminescence (PL) spectroscopy measurements. The co-doped CdS/ZnS nanocrystals show two peaks; the sharp emission peak is due to CdS quantum dot at 440 nm while the broad emission peak (520–650nm) is due typical to Co-Ni ions as compared to undoped CdS/ZnS nanocrystals.
