Abstract

Innovative reproducible synthetic methods such as hydrothermal autoclave and organometallic injection synthetic route provide efficient, safe and convenient alternative pathway for the synthesis of high quality semiconductor quantum dots. Cadmium selenide (CdSe) QDs was successfully synthesized via one-step hydrothermal autoclave and organometallic injection synthetic route at 195°C.The resultant samples were characterized using optical absorption spectroscopy (UV-vis), fluorescence spectroscopy (PL), scanning electron microscopy (SEM), atomic force microscopy (AFM) and transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray analysis (EDX) and X-ray diffraction spectroscopy (XRD). Information on the surface morphology differences were attributed to the nucleation growth and QDs formation mechanisms. Resultant samples were stable for about six months at 23°C.
