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).}, cin = {FS-DO}, ddc = {670}, cid = {I:(DE-H253)FS-DO-20120731}, pnm = {899 - ohne Topic (POF3-899)}, pid = {G:(DE-HGF)POF3-899}, experiment = {EXP:(DE-H253)D-I-20150101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000539377300001}, doi = {10.1016/j.optmat.2020.109751}, url = {https://bib-pubdb1.desy.de/record/441952}, }
