CD-BASED-CHALCOGENIDE/CDS CORE-SHELL NANOMATERIAL, DEFECTIVE/DEFECT-FREE CORE NANOCRYSTAL, METHODS AND APPLICATIONS THEREOF

摘要

The present disclosure relates to semiconductor nanomaterials, preferably quantum dots (QDs), methods to obtain said nanomaterials and applications thereof. More particularly, the present disclosure relates to Cd-based-chalcogenide/CdS core-shell nanomaterial starting from a defective core nanocrystal and thick shell structure (greater than 3 nm thickness) with a high quantum yield (greater than 80%), and methods of obtaining the said nanomaterial. The present disclosure further relates to defective/defect-free Cd-based-chalcogenide core nanocrystal and method for synthesizing the defective/defect-free core. The present disclosure also relates to devices and applications of said nanomaterial and the defective/defect-free Cd-based-chalcogenide core.
