Perspectives on the Physical Chemistry of Semiconductor Nanocrystals
Abstract
Semiconductor nanocrystals exhibit a wide range of size-dependent properties. Variations in fundamental characteristics ranging from phase transitions to electrical conductivity can be induced by controlling the size of the crystals. The present status and new opportunities for research in this area of materials physical chemistry are reviewed.

The effective bandgap of QDs and hence their photoluminescence can be tuned by either modifying their radius or their composition.
“As a result, the effective bandgap of QDs and hence their photoluminescence (PL) can be tuned by either modifying their radius [14] or the composition: CdS [15], CdSe [16], and CdTe [17] in the visible spectra and PbS [18], PbSe [19], and InAs [20] in the near infrared.”

The emission wavelength can be tuned by changing the material forming the QDs and their size.
“In addition taking in account that the emission wavelength can be tuned by changing the material forming the QDs and their size [14][15][16][17][18][19][20], it has demonstrated the applications of colloidal QDs in LEDs technology [35].”

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.
