Charge-Tunable Optical Properties in Colloidal Semiconductor Nanocrystals
Abstract
The optical properties of colloidal semiconductor nanocrystals are found to be extremely sensitive to excess electrons. Electrons in the lowest quantum-confined state of the conduction band of CdSe and (CdSe)ZnS nanocrystals quench photoluminescence by several orders of magnitude, at the same time, leading to a strong, mid-infrared intraband absorption and bleaching of the interband exciton transitions. Surface electrons are also efficient in quenching photoluminescence, but a passivating layer of wider band gap ZnS can reduce their influence. The results suggest that single-electron switching of photoluminescence may be feasible with improved core/shell structures of semiconductor nanocrystals.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
