Light given off by a substance after it absorbs energy, like UV light, and then re-releases it as visible light — this is why some markers, clothes, or rocks glow under a "black light." It's different from just being colored: fluorescence means the object is actually giving off its own light in response to another light source.
螢光；(物質受激發後)發光現象
組成fluor- (from "fluorite", the mineral where this glow was first studied) + -escence (the state of becoming)

- A multi-institution US research team has combined some creative chemistry, fluorescence microscopy and laser-driven microballistics to gain a clearer view of just what happens in a high-strain-rate impact, and to tease out the relative contribution of different kinds of energy dissipation within the target (Nat. Commun., doi: 10.1038/s41467-024-52663-1).
