Abstract
Spectroscopic properties of Ce3+ ions in GdAlO3 crystal are presented. At least three Ce3+ nonequivalent centres (multisites) are present in this crystal. Energy transfer from the Ce3+ main in the UV emitting c entres to the Ce3+ green emitting centres is observed. Ce3+ fluorescen ce decays are either fast (1.5-20 ns) or slower due to complicated pro cesses of energy transfer and migration (Ce3+)(i) --> (Gd3+)(n-step) - -> (Ce3+)(j) (energy transfer through Gd3+ sublattice).
