CdS semiconductor nanocrystals(NCs) were synthesized by microwave-hydrothermal method in water solution.In comparison,with the synthesis of NCs in organic solvents,the growth surroundings of aqueous NCs were more poisonous and costly.The XRD and TEM provided direct evidence for a cubic zinc blende structure of bulk CdS crystal.Moreover,the CdS NCs had excellent photoluminescence properties by the characterizations of absorption spectra and luminescence spectra.This method proved that CdS NCs suited to grow in aqueous condition.
