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-in-the-dark" materials which are "charged" by exposure to light.
WebApr 8, 2024 · In phosphorescence, the energized atoms take time to settle down to the low energy level. The energy level of the emitted photon particles is lower than those were absorbed in fluorescence. The same happens in the phosphorescence but the wavelength of the emitted photons is longer than fluorescence. Webphosphorescence in American English. (ˌfɑsfəˈresəns) noun. 1. the property of being luminous at temperatures below incandescence, as from slow oxidation in the case of phosphorus or after exposure to light or other radiation. 2. a luminous appearance resulting from this. 3. any luminous radiation emitted from a substance after the removal ...

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.
