Abstract

The effect of nonradiative processes on spectroscopic properties of the Y₃Ga₅O₁₂ crystal doped with Cr⁺⁴ has been examined. For this reason, the absorption, emission and photoacoustic spectra of the same have been measured and analyzed. For the interpretation of the obtained result the role of the nonradiative interconfigurational transfer between highly excited vibronic levels was considered. It is concluded that this relaxation mode is probably the reason for almost purely nonradiative character of the Cr⁺⁴ centers in the investigated medium.
