Abstract

Differently from the normal three single precursor method to produce colloidal ternary quantum dots (QDs), herein ternary Ag₃SbS₃ quantum dots (QDs) with efficient near-infrared (NIR) luminescence have been prepared by a new facile in situ conversion of Ag nanocrystals (NCs) with a binary Sb/S organic precursor Sb(C₉H₁₉COOS)₃ under low temperature. The unprecedented construction evolution from Ag NCs to Ag₃SbS₃/Ag hetero-structure and final monodisperse Ag₃SbS₃ QDs has been demonstrated. These novel Ag₃SbS₃ QDs exhibit efficient NIR emission at ≈1263 nm and possess high colloidal stability.
