摘要：

The luminescence excitation spectra and the electron excitation relaxation features of Al2O3, YAP, YAG, and YGG crystals are discussed from the viewpoint of the specificity caused by the complexity of the unit cell. The branching of relaxation is observed between the usual channel, characteristic of the simple wide-band insulators, and the one connected with the nonbonding states appearing in complex oxides. A model describing such branching is proposed. For comparison, the luminescent features of a CaWO4 crystal containing clearly separable oxyanion structures (in contrast to the crystals mentioned) are studied.
