Abstract

Following photoexcitation of an impurity ion in a crystal, phonons are emitted associated with the nonradiative energy transfer from 'hot' ion into the lattice environment. The nonequilibrium vibronic states populated during the nonradiative relaxation of Cr4+ impurity ions in Mg2GeO4, were measured using upconverted hot luminescence to obtain information on the phonon modes and electronic bottlenecks involved.
