Выдержка
Time-resolved spectra, decay kinetics and polarization of the transient optical absorption induced by irradiation of additively colored BeO crystals with electron pulses have been studied. It has been established that the two bands at 3.8 and 4.3 eV of the transient optical absorption are due to the transitions between triplet and singlet excited states of F-centres in BeO. The polarization of excited F-centres absorption is discussed on the basis of analysis of the splitting of singlet and triplet states in crystalline field of the C3v symmetry.
