Abstract

A general, one-pot, single-step method for producing colloidal silver chalcogenide (Ag₂E; E = Se, S, Te) nanocrystals is presented, with an emphasis on Ag₂Se. The method avoids exotic chemicals, high temperatures, and high pressures and requires only a few minutes of reaction time. While Ag₂S and Ag₂Te are formed in their low-temperature monoclinic phases, Ag₂Se is obtained in a metastable tetragonal phase not observed in the bulk.
