Abstract

The energy of Cr4+ local modes and the energy and dynamics of Mg2SiO4 phonon modes involved in the nonradiative relaxation of photoexcited impurity Cr4+ ions in forsterite crystal were measured. The experimental results suggest that resonance in energy between local vibrations of the impurity ion and lattice (phonon) modes of the host crystal plays a crucial role in selecting the phonons which participate in the nonradiative relaxation of the photoexcited ions in crystals.
