Semiconductors have a valence band that is filled with electrons and an empty conduction band separated by a band gap (also called energy gap). For an electron to be excited into the conduction ...

Qdot Conjugates are engineered fluorescent materials consisting of a Quantum dot nanocrystal core and shell of CdSe and ZnS, respectively. The nanocrystal is coated with an organic molecular layer ...

A new technique for growing quantum dots has not only found a new, more efficient way to build a useful type of quantum dot, but also opened up a whole group of novel chemical materials for future ...

and colloidal core-shell quantum dots (QDs) have achieved high electroluminescence performance. However, materials containing heavy metals such as lead-halide perovskites and CdSe QDs cause serious ...

This property is exploited in applications such as quantum dots, phosphors, and LEDs. Defects can also introduce absorption bands, modifying the optical absorption spectrum of the material. In CdSe ...
