A synthetic method for transition-metal chalcogenide nanocrystals.

In this paper, we prepared a series of chalcogenide semiconductor nanocrystals in controllable shape and size via a facile wet route using metal nitrates and sulfur or selenium powder as precursors and octadecylamine (ODA) as solvent. The as-obtained chalcogenides included CdS, MnS, Ag(2)S, PbS, Cu(1.8)S, Bi(2)S(3), ZnS, Zn(x)Cd(1-x)S, as well as Ag(2)Se… (More)
