Near-infrared emitting Cu-In-Se/ZnS core/shell quantum dots: aqueous synthesis and sulfur source effects dagger

Key Words:

Abstract:The present study reports an aqueous synthesis approach towards Cu-In-Se/ZnS quantum dots with emission in the near-infrared spectral range. The photoluminescence of the dots can be effectively controlled by adjusting the sulfur source, to achieve increased quantum yields (four times higher) and red-shifted emission peaks (from 809 nm to 830 nm).
