The distance between the electron in the conduction band and its hole in the valence band is called the Bohr radius. The diameter of a QD is in the same order as its exciton Bohr radius ...

"We attribute this suppression to a reduced exciton Bohr radius and exciton diffusion coefficient, as extracted from optical spectroscopy measurements." The researchers evaluated their LEDs in a ...

This confinement is effective when the size of the particle is comparable to or smaller than what is called the “exciton Bohr radius” of the material, which is typically a few nanometers This ...
