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

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).

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 …

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 …

Nov 24, 2025 · Fluorescence is a type of photoluminescence, described as the temporary absorption of light energy by a substance followed by the immediate re-emission of that energy as light. The …

What is fluorescence? Fluorescence is a light signal detected when a chemical compound called a fluorophore absorbs energy at a specific wavelength, causing it to become excited.

The phenomenon of fluorescence was known by the middle of the nineteenth century. British scientist Sir George G. Stokes first made the observation that the mineral fluorspar exhibits fluorescence …

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 …

Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at …
