The luminescence characteristics of M3+: Al2O3 crystals, where M3+ stands for an isoelectronic cation impurity with a filled electron shell, namely, Sc3+, Y3+, or La3+, were studied. The luminescence of excitons bound (BE) to these impurities was det

Among rare-earth ions Ce 3+ has the simplest electron configuration - 4f 1 . Its 4f-5d transitions have an energy of approximately 6.3 eV for a free ion and are quite allowed. Thus, the introduction of Ce 3+ into the crystal with wide enough forbidde
