Abstract

Cu₂SnS₃ nanocrystals with metastable zincblende and wurtzite structures have been successfully synthesized for the first time. Alloyed (ZnS)_x(Cu₂SnS₃)_1−x and (CuInS₂)_x(Cu₂SnS₃)_1−x nanocrystals with arbitrary composition (0 ≤ x ≤ 1) and ultra-broad tunable band gaps (3.63 to 0.94 eV) were obtained.
