title: Colloidal synthesis of ternary AgFeS2 nanocrystals and their transformation to Ag2S-Fe7S8 heterodimers.
abstract: Ternary-/hetero-nanocrystals: a facile one-pot colloidal route for controlled synthesis of ternary AgFeS2 nanocrystals, which have a band gap of 1.21 eV, is presented for the first time. Such ternary AgFeS2 nanocrystals can transform to Ag2 S-Fe7 S8 heterodimers by internal thermal reaction at elevated temperature, providing a new route to synthesize semiconductor hetero-nanostructures.
