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 ...

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 ...

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 ...
