ZnS anisotropic nanocrystals using a one-pot low temperature synthesis

We report a simple, low temperature and scalable synthesis of wurtzite ZnS anisotropic nanocrystals performed under air. The reaction between a zinc salt (nitrate or chloride) with thioacetamide and amines at 60 °C yields ZnS nanoplatelets or nanowires absorbing in the ultra-violet region with a full width at half maximum between 11 nm and 15 nm.
