Low-temperature synthesis of hexagonal (Wurtzite) ZnS nanocrystals.

We report a low-temperature (150 degrees C) and simple synthesis of quasi-monodispersed and uniform hexagonal (Wurtzite) ZnS nanocrystals in ethylene glycol medium. The samples structures were characterized with X-ray diffraction technique and transmission electron microscopy. It is believed that ethylene glycol medium plays a key role in forming hexagonal ZnS which is a stable phase at high temperatures.
