✦ Synopsis

Rcceivcd 5 alarch 1984 Non-radiative rchsation by multi-phonon emission has been invcstigatcd for the 5D1 level of Eu3+ in ?iaGdTiO,l. The SD,+ SDo relaxation rate has been evaluated in the temperature region between 4.2 K and room tempentUre. The temper-OtUrc dcpcndence of the relaxation rate points to a fifth-order process. The frequency of the emitted phonons corresponds with that of the Cd-O strerching vibrations.
