Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the … See more Photoluminescence processes can be classified by various parameters such as the energy of the exciting photon with respect to the emission. Resonant excitation describes a situation in which photons of a … See more In a typical PL experiment, a semiconductor is excited with a light-source that provides photons with an energy larger than the See more Photoluminescence spectroscopy is a widely used technique for characterisation of the optical and electronic properties of semiconductors and … See more • Klingshirn, C.
