TL;DR: Although the wurtzite counterparts grown under the same conditions showed optical properties similar to those reported in the literature, zinc-blende CdSe/CdS core/shell nanocrystals demonstrated surprisingly different optical properties, with ensemble single-exponential photoluminescence decay, significant decrease of photolumscence peak width by the shell growth, and comparatively high photolUMinescence quantum yields.

TL;DR: Synthetic control of exciton behavior implies surface engineering of quantum dots, including surface cation/anion stoichiometry, organic ligands, inorganic epitaxial shells, etc, and concentration and location of the dopant ions within a nanocrystal lattice are found to be as important as control of the surface states.

TL;DR: This work explored possibilities to obtain colloidal quantum dots (QDs) with ideal photoluminescence properties, i.e., monoexponential PL decay dynamics, unity PL quantum yield, ensemble PL spectrum identical to that at the single-dot level, single- dot PL nonblinking, and antibleaching.

TL;DR: Type-II quantum dots were applied for QDs-sensitized solar cells for the first time and showed prominent absorbed photon to current conversion efficiency.

TL;DR: Entropic ligands are introduced to maximize the intramolecular entropic effects, which increases solubility of various nanocrystals by 10(2)-10(6) by means to greatly improve performance of nanocrystal-based electronic and optoelectronic devices.
