Cadmium precursors with acetylacetonate, less toxic than Me2Cd give one-step synthesis procedure for CdSe quantum dots (QDs). Powder X-ray diffraction shows hexagonal structure of QDs. TEM and HRTEM images of QDs reveal that they are almost mono disperse and size is of the order of  5 nm. It is observed that the precursor and reaction time affect size. The size of QDs increases with reaction time. The temporal growth was monitored by UV−Vis spectroscopy (up to 20 min).

Keywords: Cadmium selenide, X-ray diffraction, Temporal growth.
