  Monodisperse Zn7.23Cd2.77S10 nanoparticles with uniform shape and   a narrow size distribution were synthesized by a room temperature   reaction, followed by a 200℃ heat-treatment in an autoclave,   using Na-oleate and oleic acid as surfactant and ligand,   respectively. This method achieves a complete separation of the   nucleation and growth. X-ray diffraction (XRD), transmission   electron microscopy (TEM) and high-resolution TEM   characterizations showed that the monodisperse nanoparticles had   a poly-crystalline hexagonal structure with a uniform crystallite   size of 20μm with spike-like morphology and a very rough surface.   The photoluminescence (PL) spectra of Zn7.23Cd2.77S10 had   blue-shifted with a peak at 485μm.
