Phosphorescence definition simple
WebJan 30, 2024 · Fluorescence occurs when an atom or molecules relaxes through vibrational relaxation to its ground state after being electrically excited. The specific frequencies of excitation and emission are dependent on the molecule or atom. S0 + hνex = S1 where hν is a photon energy with h is Planck's constant and ν is the frequency of light, WebPhosphorescence is light emitted after exposure to radiation, or produced by something that doesn't produce flame or heat. An example of phosphorescence is the light from a glow …

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 fluorescence, such as those seen in laser mediums like the common ruby, phosphorescent materials "… WebPhotoluminescence is the emission of light from a material following the absorption of light. 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.

WebJan 30, 2024 · One direct transition is phosphorescence, where a radiative transition from an excited triplet state to a singlet ground state occurs.This is also a very slow, forbidden transition. Another possibility is delayed fluorescence, the transition back to the first excited singlet level, leading to the emitting transition to the ground electronic state.
