Abstract :
Intrinsic ultra-fast scintillations at pulsed X-ray excitation were found in LiCaAlF6 and LiSrAlF6. Radiative recombination features of Ce-doped crystals are explained by differences of lattice properties, defect structure and Ce3+ ion environment in these crystals. The role of exciton formation, electron and hole traps, and energy transfer to the activator centers are discussed.
