WebAug 8, 2024 · Fluorescence and phosphorescence are types of molecular luminescence. A molecule of analyte absorbs a photon and results in an excited species. That excited species can then emit energy (photon, heat). The emission spectrum can provide qualitative and quantitative analysis. Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately … See more The term phosphorescence comes from the ancient Greek word φῶς (phos), meaning "light", and the Greek suffix -φόρος (-phoros), meaning "to bear", combined with the Latin suffix -escentem, meaning "becoming … See more Most photoluminescent events, in which a chemical substrate absorbs and then re-emits a photon of light, are fast, in the order of 10 See more Some examples of glow-in-the-dark materials do not glow by phosphorescence.
