Differently from the normal three single precursor method to produce colloidal ternary quantum dots (QDs), herein ternary Ag 3 SbS 3 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(C 9 H 19 COOS) 3 under low temperature. The unprecedented construction evolution from Ag NCs to Ag 3 SbS 3 /Ag hetero‐structure and final monodisperse Ag 3 SbS 3 QDs has been demonstrated. These novel Ag 3 SbS 3 QDs exhibit efficient NIR emission at ≈1263 nm and possess high colloidal stability.
