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 approximate to 1263 nm and possess high colloidal stability.
