Ternary‐/hetero‐nanocrystals: a facile one‐pot colloidal route for controlled synthesis of ternary AgFeS 2 nanocrystals, which have a band gap of 1.21 eV, is presented for the first time. Such ternary AgFeS 2 nanocrystals can transform to Ag 2 S‐Fe 7 S 8 heterodimers by internal thermal reaction at elevated temperature, providing a new route to synthesize semiconductor hetero‐nanostructures.
