Fluorescent lamp - Wikipedia
https://en.wikipedia.org/wiki/Fluorescent_lamp
WEBA fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.

WEBApr 5, 2023 · Fluorescence Definition and Examples. Fluorescence is photoluminescence where atoms absorb light and rapidly emit photons with a longer wavelength. 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 (UV) light.

WEBJan 30, 2023 · Page ID. Fluorescence, a type of luminescence, occurs in gas, liquid or solid chemical systems. Fluorescence is brought about by absorption of photons in the singlet ground state promoted to a singlet excited state. The spin of the electron is still paired with the ground state electron, unlike phosphorescence.

WEBJun 13, 2011 · Fluorescence is a form of photoluminescence, i.e., the emission of photons after a material is illuminated with light [2]. The emitted light has a longer wavelength than the exciting light which is known as the Stokes shift. Molecules and atoms can exist in various quantum states with different energy levels.

Fluorescent Lights: What Are They and How Do They Work?
https://www.familyhandyman.com/article/how-do-fluorescent-lights-work/
WEBDec 20, 2023 · Fluorescent lights are an energy-efficient lighting technology found in homes, commercial spaces, offices, schools and industry. They’re called “fluorescent” because of the way they produce light. If something “fluoresces,” it emits light in reaction to absorbing light or other electromagnetic radiation, usually of a different wavelength.
