Optical spectroscopy reveals transition of CuInS2/ZnS to CuxZn1−xInS2/ZnS:Cu alloyed quantum dots with resultant double-defect luminescence

The structure and luminescence mechanisms of the CuInS2 quantum dots (QDs) after epitaxial growth of ZnS shell are in debate. The light absorption/emission spectroscopy reveals that after ZnS shell growth the cation diffusion at the CuInS2/ZnS interface results in formation of the alloyed CuxZn1− xI...
