Phosphorescence - Wikipedia When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs
PHOSPHORESCENT definition | Cambridge English Dictionary Early computer monitors used a phosphorescent backing on the inside of the screen to help display colors When the radiation hits the phosphorescent coating on the inside of the bulb, the phosphors glow
What Is Phosphorescence? (with pictures) - AllTheScience Classified as a type of photoluminescence, the tiny molecules in phosphorescent materials soak in the energy from light photons Once the molecules have absorbed the photons, they radiate that light
Phosphor - Wikipedia Phosphorescent materials are used where a persistent light is needed, such as glow-in-the-dark watch faces and aircraft instruments, and in radar screens to allow the target 'blips' to remain visible as the radar beam rotates CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number
