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.
三元/杂化纳米晶体：首次提出了一种简便的一锅胶体路线，用于控制合成具有 1.21eV 带隙的三元 AgFeS2 纳米晶体。这种三元 AgFeS2 纳米晶体可以在高温下通过内部热反应转化为 Ag2S-Fe7S8 杂二聚体，为合成半导体杂化纳米结构提供了新途径。
