Abstract

CdSe nanoparticles were prepared through a cetyltrimethyl ammonium bromide (CTAB) assisted hydrothermal method. In this route, cadmium salt and SeCl4 as precursors and hydrazine hydrate (N2H4·H2O) as reductant were used. By varying the cadmium salt, reaction time, temperature, surfactant and molar ratio of Cd:Se:CTAB, the method permits us to synthesize nanoparticles with diameters less than 20 nm. SEM and TEM images show the morphology and particle size of the as-synthesized CdSe. XRD patterns show a pure hexagonal phase of CdSe. Chemical composition of nanoparticles is characterized by EDS. It is found that uniform CdSe nanoparticles are successfully produced from sulfate salt using 2 ml of hydrazine at 180 °C for 12 h.
