Abstract
The authors present a detailed analysis of the emission band at 13000 cm-1 in KZnF3:Cr3+. The spectrum structure at low temperature is interpreted in terms of zero-phonon lines and their replicas which are due to interaction with localised modes of both the defects and phonons of the host lattice.Keywords
