Abstract
An analysis of the crystal field distribution and distribution of the electron lattice coupling of disordered materials doped with Cr3+ ions is presented. The theoretical background contains the extended crystal field model based calculations of the emission line-shape and kinetics. The multi-site effect in the gallogermanate and lithium tantalate crystals and aluminosilicate glasses is analysed in detail.
