Abstract

Nonthermal plasmas can produce high quality nanocrystals in a continuous process without requiring solvents. A nonthermal plasma process is demonstrated to synthesize stoichiometric Cu₂S nanocrystals, which show no signs of oxidation by spectrophotometry after 2 months in the ambient when stabilized with oleylamine and dispersed in toluene.
