TL;DR: This work develops core/shell hetero-nanocrystals engineered in such a way as to spatially separate electrons and holes between the core and the shell (type-II heterostructures), which breaks the exact balance between absorption and stimulated emission, and allows for optical amplification due to single excitons.

TL;DR: This result indicates that Ru complexes can be sensitized by CdSe NQDs, which opens interesting opportunities for designing new types of photocatalytic materials for solar energy conversion applications.

TL;DR: A method for determining the spatial extent of the localized electron in the plane of the interface has been developed and was measured to be on the order of a single adsorbate molecule.

TL;DR: In this article, inverted core-shell nanocrystals (NCs) are studied, in which a core of a wide-gap semiconductor (ZnSe) is overcoated with a shell of a narrower gap material (CdSe).

TL;DR: In this article, a simple model for analyzing optical gain in ultrasmall semiconductor nanocrystals in the presence of exciton−exciton (X−X) interactions was developed, showing that if the X−X interaction is repulsive and its energy is large compared to the ensemble line width of the emitting transition, optical gain can occur in the single-exciton regime without involvement of multiexcitons.
