Abstract
Luminescence quenching which originates from the interaction of closel y spaced electronic excitations (EEs: electrons, core- and valence-ban d holes, excitons, etc.) is considered. 'Reactions' between them at a distance shorter than that of dipole-dipole interaction are discussed. Creation of regions with high local density of EEs by VUV and XUV pho tons is demonstrated. Features of this type of quenching specific for different regions of excitation and different crystals are illustrated by experimental examples.
