英英释义

Photoluminescence

Photoluminescence (abbreviated as PL) describes the phenomenon of 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 (excitation by photons), hence the prefix photo-.
