Abstract
The spectral and kinetic parameters of radiation-stability scintillato rs based on alkali-earth oxides and fluorides (pure and doped Ce3+-ion s) and some alkaline halides under high intensity X-ray synchrotron ra diation of the VEPP-3 storage ring are studied. A strong decrease of t he decay time and the luminescence quantum yield and a change of the s pectrum under high intensity SR are observed. The effects have a commo n nature for all crystals and are connected with an increase of the no n-radiative energy transfer efficiency from the lower excited states o f the luminescence center under high intensity of the excitation.
