      Luminescence - Luminescence - Luminescence physics: The emission of visible light (that is, light of wavelengths between about nanometres and nanometres, corresponding to the region between deep red and deep violet) requires excitation energies the minimum of which is given by Einstein’s law stating that the energy (E) is equal to Planck’s constant (h) times the frequency of light   The nature of luminescence centers created by La 3+ isoelectronic impurities (IIs) in Y 3 Al 5 O 12 (YAG) crystals has been considered. The La 3+ dopant in YAG crystals gives rise to intensive UV luminescence in the complex band peaked at eV at K with a decay time of the main component of ns. It has been shown that the complex UV emission band in YAG:La crystals in the 10– K

    Ilya Obodovskiy, in Radiation, General Definitions. Luminescence is emission in the optical range of the visible, ultraviolet, or infrared light, which is an excess over the thermal radiation emitted by the substance at a given temperature, and continues after absorbing the excitation energy for a time that is significantly longer than the period of the light :// Time-resolved spectra of the luminescence in oxygen-deficient α-Al 2 O 3 crystals were studied using synchrotron radiation. The UV luminescence with hv = eV and τ = ns was detected in addition to the known slowly relaxing component (hv = 3 eV, τ = 34 ms) of the emission transition of the F-center under excitation near 6 ://
