bound-bound transition comparison table
Subject has definition has synonym is a kind of is an instance of
fluorescenceThe emission of light at one wavelength, the green say, following absorption of light with a much shorter wavelength such as the ultraviolet. The UV photon parts with its energy by ejecting the electron into a high-energy level from which it cascades back down, releasing photons of lower energy and therefore longer wavelengths. A material which has this property is called a phosphor.world pointemission 
spontaneous emissionRadiation emitted by an isolated body.world point emission
stimulated emissionRadiation emitted by a body, such as an atom, when it is bombarded by radiation. The stimulated radiation has the same wavelength and direction as the bombarding radiation.induced emission emission
