Phosphor atome
A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow when struck by an electron beam (cathode rays) in a cathode-ray tube. WebAug 24, 2024 · The electron configuration of a Phosphorus atom in its ground state is 1s2 2s2 2p6 3s2 3p3, but when it is in an excited state, the electrons from 3s orbital get unpaired. There are five half-filled orbitals: one s orbital, three p orbitals, and one d orbital. All these five orbitals accommodate one valence electron of the Fluorine atoms.
