Selvin, for instance, takes a core of cadmium selenide
and then adds a sulfur atom and a chain of 11 carbon atoms.
Selenium was not detected in any samples, ruling out the presence of cadmium selenide
In particular, the electrophoretic deposition of cadmium selenide
(CdSe) nanocrystals is being studied due to the diverse applications of these semiconductor nanocrystals, including fluorescent tags in biological imaging (Stroh et al.
Tyagi notes that cadmium selenide
is a toxic metal, and so one of the hurdles to overcome with regard to this particular example would be finding a replacement material.
We are witnesses to the excitement of discovery represented in such images as cadmium selenide
nanocrystals, self-assembled polyhedra, yeast colonies, and mouse embryo lungs, thereby illustrating the book's educational value.
5-nm-dia cadmium selenide
(CdSe) yields 630-nm emission, while 3-nm-dia CdSe leads to 520-nm emission, with in-between sizes producing intermediary colors (up to ten separate quantum dot colors can be generated using these two seminconductors).

4:15 SIZE DEPENDENT STUDY OF CADMIUM SELENIDE
QUANTUM DOTS FABRICATED BY PHOTOLITHOGRAPHY **, Volker Beutner *, Raghuveer R Gadipalli.
Now a team of researchers from the University of Pennsylvania has shown that nanoscale particles, or nanocrystals, of the semiconductor cadmium selenide
can be "printed" or "coated" on flexible plastics to form high-performance electronics.
Scientists from the University of Notre Dame used nano-sized particles of titanium oxide and covered them in either cadmium sulphide or cadmium selenide
The dots, from 2 to 10 nanometers (nm) across, are typically made of cadmium selenide
or lead sulfide.
Certain metal chalcogenides are sufficiently good photoconductors to be used in video cameras, and others such as cadmium selenide
are being studied for use in thin film transistors.
