- In the case of an excited atomic nucleus decaying by gamma radiation in a spontaneous emission of electromagnetic radiation, the arbitrarily small disturbance comes from quantum vacuum fluctuations.
- Spontaneous emission cannot be explained by classical electromagnetic theory and is fundamentally a quantum process.
- Observationally, the Schrödinger equation underlying quantum mechanics could explain the stimulated emission of radiation from atoms, where an electron emits a new photon under the action of an external electromagnetic field, but it was unable to explain spontaneous emission, where an electron spontaneously decreases in energy and emits a photon even without the action of an external electromagnetic field.
- It offers high luminous efficacy due to the narrow emission bands; but the generally low quantum efficiency and too little absorption in the UV-A to blue spectral region hinders commercial application.
- Doping is additionally used to determine the wavelength of photon emission.
- This occurs because excited molecules usually decay to the lowest vibrational level of the excited state before fluorescence emission takes place.
- Energy emission can occur when a moving electron is deflected by a charged particle, such as a proton.
- Likewise, through spontaneous emission, an electron in a higher energy state can drop to a lower energy state while radiating the excess energy as a photon.
- Fluorescent emission peaks at around 460 nm (bright blue/cyan hue).
- In 1905, Albert Einstein published a paper "On a heuristic viewpoint concerning the emission and transformation of light" explaining photoelectric effect based on quantized electromagnetic waves.
- Manipulation of the band gap allows for the absorption and emission of specific wavelengths of light, as energy is inversely proportional to wavelength.
- The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.
- The decay of one of the proton's up quarks into a down quark can be achieved by the emission of a W boson.
- The mechanism of producing radiation in a laser relies on stimulated emission, where energy is extracted from a transition in an atom or molecule.
