| 中文摘要 | The wurtzite-derived Cu2InSn(S1-xSex)(4) alloys are studied for the first time through combining theoretical calculations and experimental characterizations. Ab initio calculations predict that wurtzite-derived Cu2ZnSnS4 and Cu2ZnSnSe4 are highly miscible, and the band gaps of the mixed-anion alloys can be linearly tuned from 1.0 to 1.5 eV through changing the composition parameter x from 0 to 1. A synthetic procedure for the wurtzite-derived Cu2ZnSn(S1-xSex)(4) alloy nanocrystals with tunable compositions has been developed. A linear tunable band-gap range of 0.5 eV is observed in the synthesized alloy nanocrystals, which shows good agreement with the ab initio calculations. |
