Abstract
The spectral features and structural factors influencing the formation of luminescence bands of Ce3+ ions in YAG:Ce crystals are considered. The energy levels of the 4f shell of Ce3+ ions occupying both dodecahedral and octahedral sites of the crystal lattice have been determined. The participation of Ce3+ ions and \({\text{Ce}}_{{{\text{Al}}}}^{{3 + }}\) ions in the structure of the luminescence band was shown and the multicenter structure of Ce3+ ions in the 4f ↔ 5d transitions of the activator was determined.
