N2 - The luminescence spectra and decay kinetics are measured within 80-300 K for the set of mixed YF3-GdF3 single-crystal fluoride hosts doped by the Ce3+ and Me2+ (Me ≤ Mg, Ca, Sr, Ba) ions. For certain Ce and Me concentration ranges we observe creation of the Ce3+-distorted luminescence centre with the emission maximum around 380-390 nm. Energy migration through the Gd sublattice and a transfer to the Ce3+-distorted centre is evidenced and modelled using a simple Stern-Volmer approximation.
