a type of light emission that is the same as fluorescence except for a delay between excitation and de-excitation, which provides an afterglow. The delay is caused by atoms being excited to energy levels that do not decay rapidly. The afterglow may last from fractions of a second to hours, or even days, depending on the type of material, temperature, and other factors.

∙ 12y agoPhospheresnce is closely related to flouroescence. Like fluorescent materials, phosphorsecant materials give off visible light when excited by energy like UV light. However, while flouroesce material quits emitting light when UV light is turned off, phosophorescant material continues to give off light. The extra duration varies from phosphorescent material to phospheresant material. Sometimes phosopherescant material gives off light for a fraction of a second longer, other material for hours or even days. The phosophorescance can be caused by UV light, but also visible light, X-rays, infrared and other light. As with fluorescence, the color, brightness and duration of the phosphorescence is caused by the atomic make up of the material.
Hope that helps some

Phosphorescence is similar to what other source of light?

What is phosphorescent light?
Ever after the light falling on the substance is removed the substance continues glowing. This property is known as phosphorescence.
What source of light is similar to Phosphorescence?
Bioluminecence , or a symbiotic arraignment between an animal and a bacteria, is a natural light source given off by a living organism.
How is light produced by phosphorescence?
In simple terms, phosphorescence is a process in which energy absorbed by a substance is released relatively slowly in the form of light. This is in some cases the mechanism used for "glow-in-the-dark" materials which are "charged" by exposure to light. Unlike the relatively swift reactions in a common fluorescent tube, phosphorescent materials used for these materials absorb the energy and "store" it for a longer time as the processes required to re-emit the light occur less often. I hope that answers your question!
What is the synonym of phosphorescence?
