A simple, open air method to synthesize monodisperse and size selective PbSe quantum dots is reported here. PbCl2 complexed with oleylamine was used as the Pb precursor. Se powder dissolved in 1-octadecene was used as the Se precursor. The size and shape of the PbSe quantum dots were controlled by changing injection temperature, precursor concentrations, reaction temperature, and reaction time. The sizes of the PbSe quantum dots ranged from 6.5 nm to 15.0 nm with a standard deviation of 1.9-6.9%. The shapes of the PbSe quantum dots were either spherical (< similar to 9-10 nm) or cubic (>similar to 9-10 nm). The as-synthesized PbSe quantum dots were characterized by transmission electron microscopy, high resolution transmission electron microscopy, selected area X-ray diffraction, energy dispersive X-ray spectroscopy, and powder X-ray diffraction.
