WebApr 9, 2024 · The main difference between fluorescent and phosphorescent is, fluorescence is the absorption of energy by atoms or molecules followed by immediate emission of light or electromagnetic radiation. On the other hand, phosphorescence is the absorption of energy by atoms or molecules followed by delayed emission of electromagnetic radiation. 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.

Phosphorescence - Wikipedia

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. WebOne radiative mechanism by which excited electrons may relax is a light-emitting transition from the lowest excited state (S1) to ground state (S0) in a fast (10-9to 10-6sec) process called fluorescence.
