Semiconductor Nanocrystal - an overview | ScienceDirect Topics Semiconductor nanocrystals (NCs) represent an important class of building blocks materials for next-generation solution-processed optoelectronic devices. The ability to control the shape and thus the spatial extent of electron and hole-wave functions enables new opportunities for materials design and performance enhancement of NC-based devices.

Developing New Nanoprobes from Semiconductor Nanocrystals The U.S. Department of Energy's Office of Scientific and Technical Information Core-shell semiconductor nanocrystal - Wikipedia Quantum dots are popular alternatives to organic dyes as fluorescent labels for biological imaging and sensing due to their small size, tuneable emission, and photostability. The luminescent properties of quantum dots arise from exciton decay (recombination of electron hole pairs) which can proceed through a radiative or nonradiative pathway.

Application of semiconductor and metal nanostructures in biology and ... Semiconductor nanocrystals are commonly used as probes for labeling cells and tissues owing to their intense, tunable fluorescence. 24, - 28 The origin of this unique physical property is quite interesting. A semiconductor crystal's band-gap energy becomes strongly size-dependent as its physical dimensions approach the exciton Bohr radius (the natural radius of an electron-hole pair in bulk).

Semiconductor Nanocrystals: The Next Thing in Fluorescent Probes "The development of semiconductor nanocrystals for biological labeling gives biologists an entire new class of fluorescent probes for which no small organic molecule equivalent exists," the authors of the Science paper wrote. "These nanocrystal probes can be complementary and in some cases may be superior to existing fluorophores."
