Abstract:
The potential of nanomaterials arises from the fine tuning of material properties by changing their composition, size and shape. Here, we show that by varying the local Cd and Te/S environment using CdTe/CdS as the host, a highly promising photovoltaicmaterial can be easily converted to an efficient photo-emitting material. Thus we demonstrate for the first time that the internal structure can be used to tune the properties of the nanomaterial leading to competing and contrasting applications.
