![]() ![]() Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after.įluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors ( fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacuum fluorescent displays, and cathode-ray tubes. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum (invisible to the human eye), while the emitted light is in the visible region this gives the fluorescent substance a distinct color that can only be seen when exposed to UV light. ![]() In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. Some features and extras mentioned in the description may also have to be purchased for real money.Fluorescent clothes used in black light theater production, Pragueįluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Please note! This game is free to play, but it contains items that can be purchased for real money. Watch the process of evolution from a monochromatic perspective.
