摘要: Colloidal quantum-confined semiconductor nanoheterostructures (SNHs) that are composed of multiple component materials in rationally designed spatial arrangements promising light harvesting and charge separation for solar energy conversion. SNHs can be engineered to exhibit type I, quasi-type II carrier localization, affecting their photophysical properties photochemical performances. Unlike bulk heterostructures, the electron hole levels distributions continuously tuned by adjusting material dimension through quantum confinement effect, providing additional control wavefunction engineering. In this article, we review recent progress using engineering absorption emission spectra, single exciton dynamics transfer (core/shell QDs dot-in-rod nanorods) as well improve performance
