How Do Excitonic Effects Influence Optical Properties?
Excitonic effects significantly influence the optical properties of nanomaterials. When an exciton recombines, it can emit a photon, making excitons essential for light emission processes. This is the principle behind the use of quantum dots in display technologies and bio-imaging. Moreover, the presence of excitons can lead to strong light-matter interactions, which are essential for developing efficient solar cells and photodetectors.
