Generalized and facile synthesis of semiconducting metal sulfide nanocrystals.

摘要: We report on the synthesis of semiconductor nanocrystals PbS, ZnS, CdS, and MnS through a facile inexpensive synthetic process. Metal−oleylamine complexes, which were obtained from reaction metal chloride oleylamine, mixed with sulfur. The mixture was heated under appropriate experimental conditions to produce sulfide nanocrystals. Uniform cube-shaped PbS particle sizes 6, 8, 9, 13 nm synthesized. size controlled by changing relative amount PbCl2 11 sized spherical ZnS synthesized zinc sulfur, followed one cycle size-selective precipitation. CdS that consist rods, bipods, tripods containing 1:6 molar ratio cadmium Spherical (5.1 sized) sulfur 2:1. v...
