Photoluminescent and superparamagnetic quantum dots

Quantum dots are semiconducting nanostructures which emit radiation over a narrow spectrum. This is caused by the restricted movement of excitons, formed when electrons are excited from the valence band into the conduction band leaving holes. When excitons relax light is emitted over a narrow spectrum due to the small crystal size, typically 2-50 nm, […]
