WebPhosphorescence is similar to fluorescence in its chemistry; however, unlike fluorescence, phosphorescent materials continue to emit light for a much longer time after the external … Phosphorescence is a type of photoluminescence related to fluorescence. 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. Instead, a phosphorescent material absorbs some of t… chingay news https://heavenly-enterprises.com
