Реферат:	eng: This paper reports on the results of the comprehensive study of the dynamics of electronic excitations in K 2Al 2B 2O 7 (KABO) crystals, obtained by low-temperature luminescence vacuum ultraviolet spectroscopy with nanosecond time resolution upon photoexcitation by synchrotron radiation. For the first time, the data have been obtained on the photoluminescence (PL) decay kinetics, PL spectra with time resolution, PL excitation spectra with time resolution, and reflection spectra at 7 K; the intrinsic nature of PL at 3. 28 eV has been established; luminescence bands of defects have been separated in the visible and ultraviolet spectral regions; an intense long-wavelength PL band has been detected at 1. 72 eV; channels of the formation and decay of electronic excitations in K 2Al 2B 2O 7 crystals have been discussed. © 2012 Pleiades Publishing, Ltd.
