As evidenced by electronic structure studies, both experimental and theoretical, such core/shell nanorod couple heterostructures can act as a platform to precisely tailor the quantum confinement of charge carriers between the constituting components within a single nano-object, generating blue fluorescence after the overgrowth of an alloyed ZnCdS layer on the heterostructures. We foresee the mechanistic insights gained and electronic structures revealed in this work would shed light on the rational design of more complex heterostructures with novel functionalities.This work was supported by the Australian Research Council (ARC) Discovery Early Career Researcher Award (DECRA) (Project ID: DE160100589), and the National Natural Science Foundation of China (Grant No. 21701015 and 21811530054).8 pagesapplication/pdfen-AU© The Royal Society of Chemistry 20192019-05-0710.1039/c9nr02443c2019-11-25
