Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray …

Apr 5, 2023 · Fluorescence is a phenomenon where certain materials rapidly (around 10 -8 seconds) emit light when they are exposed to specific types of electromagnetic radiation, typically ultraviolet …

Dec 26, 2025 · Fluorescence, emission of electromagnetic radiation, usually visible light, caused by excitation of atoms in a material, which then reemit almost immediately (within about 10−8 seconds).

Fluorescence occurs when an atom or molecules relaxes through vibrational relaxation to its ground state after being electrically excited. The specific frequencies of excitation and emission are …

Fluorescence is the result of a 3-stage process that occurs in certain molecules (e.g., polyaromatic hydrocarbons) called fluorophores.

Fluorescence is the property of some atoms and molecules to absorb light at a particular wavelength and to subsequently emit light of longer wavelength after a brief interval, termed the fluorescence …

The meaning of FLUORESCENCE is luminescence that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength and that …

Jul 25, 2025 · Fluorescence describes a natural phenomenon where certain substances absorb light and then almost immediately re-emit it as a visible glow. This process involves the transformation of …

In Physics, fluorescence is a phenomenon where a substance absorbs light or other electromagnetic radiation of a specific wavelength and then emits light of a longer wavelength.
