radiative process
1Radiative process — In particle physics, a radiative process refers to one elementary particle emitting another and continuing to exist. This typically happens when a fermion emits a boson such as a gluon or photon.ee also*bremsstrahlung …
2Radiative Cooling — The process of cooling by which a heat absorbing media absorbs heat from one source and radiates the heat away …
3Non-radiative recombination — is a process in phosphors and semiconductors, whereby charge carriers recombine without releasing photons. A phonon is released instead. Non radiative recombination in optoelectronics and phosphors is an unwanted process, lowering the light… …

9Spontaneous emission — is the process by which a light source such as an atom, molecule, nanocrystal or nucleus in an excited state undergoes a transition to the ground state and emits a photon. Spontaneous emission of light or luminescence is a fundamental process… …
