Quantum Dots Imaging

Quantum dots (QDs) are tiny semiconductor particles a few nanometres in size that have optical and electronic properties that differ from larger particles due to the quantum behaviour at nanoscales.

They are a central topic in nanotechnology. When quantum dots are illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy.

In the case of a semiconducting quantum dot, this process corresponds to the transition of an electron from the valence band to the conductance band. The excited electron can drop back into the valence band releasing its energy by emitting light.
