Luminescence, energy transfer and defects creation processes were studied at 4.2-300K for Ce^{3 +}-doped Lu₃Al₅O₁₂ crystals under excitation in the 2.5-11.5 eV energy range. The results obtained were compared with the characteristics of Y₃Al₅O₁₂:Ce crystals. It was concluded that in both systems the efficiency of energy transfer from the host lattice to the impurity ion can be noticeably increeased by the decrease of concentration of the defects responsible for the intrinsic luminescence

Luminiscence, přenos energie a tvorba defektů v Ce^{3 +}dopovaných krystalech Lu₃Al₅O₁₂ byly studovány při teplotách 4,2 - 300K při buzení v oblasti energie 2,5 - 11,5 eV. Obdržené výsledky byly porovnány s charakteristikami Y₃Al₅O₁₂:Ce krystalu
