Abstract: The work is dedicated to comparative investigation of the luminescent properties of $\mathrm{Y_{3}Al_{5}O_{12}:Pr}$ (YAG:Pr)single crystals and single crystalline films using excitation by synchrotron radiation with an energy of 3.7–25 eV in the exciton range of YAG host. We have found that the differences in the excitation spectra and luminescence decay kinetics of YAG:Pr crystals and films are caused by involving the Y$_{Al}$ antisite defects and oxygen vacancies in the crystals and Pb$^{2+}$ flux related dopants in the films in the excitation processes of the Pr$^{3+}$ luminescence. Taking into account these differences, we have determined in more detail the energy structure of the Pr$^{3+}$ ions in YAG host and estimated the differences in the energies of creation of the excitons bound with the isolated Pr$^{3+}$ions in YAG:Pr films and the dipole Pr–Y$_{Al}$ antisite defect centers in the crystal counterpart.
