Nonradiative relaxation of Cr4+-doped forsterite is studied, making use of information obtained from upconverted hot luminescence spectroscopy under a wide range of laser excitation wavelengths. Information on the upper excited electronic state, phonon modes involved in the nonradiation relaxation, and electronic bottlenecks can be obtained by upconverted luminescence.
