Phase-Controlled Synthesis of Alloyed (CdS)_x(CuInS₂)_1-x Nanocrystals with Tunable Band Gap.

ABSTRACT: Phase and band gap engineering of (CdS)_x(CuInS₂)_1-x nanomaterials is critical for their potential applications in photovoltaics and photocatalysis, yet it remains a challenge. Here, we report a precursor-mediated colloidal method for phase-control synthesis of alloyed (CdS)_x(CuInS₂)_1-x nanocrystals with tunable band gap. When CuCl, InCl₃, and Cd(AC)₂·2H₂O are used as the respective cation sources, wurtzite-structured alloyed (CdS)_x(CuInS₂)_1-x nanocrystals can be synthesized with a tunable optical band gap ranging from 1.56 to 2.45 eV by directly controlling the molar ratio of the Cd precursor. Moreover, using Cu(S₂CNEt₂)₂, In(S
