Phosphorescence definition simple
WebEnergy transfer Fluorescence and phosphorescence. In general, a small, simple molecule luminesces in the ultraviolet, and a more complex one emits near the blue-violet end of the visible spectrum.Dye molecules, on the other hand, may emit throughout the visible region, including the red end. The ground electronic state of most molecules is a singlet state. WebPhosphorescence 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 …

The word in itself is interesting in that it the combination of the Latin derived word luminescence and the Greek prefix, photo -, for light. Any luminescence that is induced by the absorption of photons is called photoluminescence.
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.
