Fluorestseeruvat

Fluorestseeruvat is a term that describes the property of certain substances to exhibit fluorescence, meaning they absorb light at one wavelength and then emit it at a longer wavelength. This phenomenon is a type of luminescence, specifically photoluminescence, where the excitation source is light. When a fluorescent material is exposed to ultraviolet (UV) or visible light, its electrons are temporarily raised to a higher energy level. As these electrons return to their ground state, they release energy in the form of photons, which are detected as visible light. The color of the emitted light depends on the specific chemical structure of the fluorescent substance. Fluorestseeruvat materials are used in a wide variety of applications, including fluorescent lamps, diagnostic imaging in medicine, security features on currency and identification documents, and in scientific research for tagging and tracing molecules. The intensity and duration of fluorescence can vary greatly among different compounds. Some substances fluoresce only while being illuminated, while others may exhibit phosphorescence, a slower form of light emission that can persist after the excitation source is removed. The efficiency of fluorescence, known as quantum yield, measures how effectively absorbed photons are re-emitted as fluorescence.
