摘要：
Inorganic nanostructures: Alloyed Cu2ZnSn(S1-xSe x)4 wurtzite nanocrystals (10nm in size) with a varying composition (x=0-1) were synthesized using a colloidal hot injection route. A photoluminescence (PL) emission study of these nanocrystals shows a compositionally tunable band-gap ranging between 0.9-1.4eV that directly correlates to the sulfur-to-selenium ratio (see picture).
