Upconverted hot-luminescence spectroscopy investigation of nonradiative relaxation in forsterite.
Upper-state nonradiative relaxation in the 3.2-1.9-eV energy region of the excited-state manifold of Cr(4+)-doped forsterite is investigated. Measurements of the upconverted hot-luminescence spectra reveal two electronic bottlenecks and several phonon modes involved in the initial steps of the vibrational relaxation at different portions of the excited-state manifold.
