abstract = {The paper is dedicated to the comparative study of the
luminescent properties of LuAG:Ce films, grown by pulse
laser deposition (PLD) and liquid phase epitaxy (LPE)
methods, using the time-resolved luminescent spectroscopy
under excitation by synchrotron radiation in the fundamental
absorption range and above the band gap of LuAG host. We
have shown the similarities and differences in the
luminescence properties of LuAG:Ce PLD and LPE grown films.
Specifically, the luminescence of Lu$_{Al}$ antisite defects
is absent in the emission spectra of both films in the room
temperature range. Meanwhile, the low intensive bands peaked
at 350 and 400 nm, corresponding to the luminescence of
excitons localized around and bound with F$^{+}$ centers,
respectively, are present in the emission spectra of LuAG:Ce
PLD films at 12 K. The energy of formation of the excitons
bound with the Ce$^{3+}$ ions, being equal to 7.52 eV at 12
K, and the energy of the onset of interband transitions of
LuAG host, being equal to 7.76 eV (at 300 K), have been
found for LuAG:Ce LPE and PLD films, respectively. We have
also found that the scintillation properties of LuAG:Ce PDL
film are worse in comparison with LPE grown film analogue
due to the significantly larger content of the slow emission
component in the scintillation decay under high-energy
excitation. Such differences between the optical and
scintillation properties of PLD and LPE films are caused by
the diffe rent conditions of their preparation (in vacuum
and in air).},
