Abstract The lifetimes of the R-lines from the 2 E level and the broad bands from the 4 T 2 level of Cr3+ ions in various garnet crystals vary with the energy separation between the 2 E and 4 T 2 levels, which change systematically with the composition of host crystal. The trend of the Cr3+ lifetimes, as well as their temperature dependences in garnet crystals, is explained by zero-point vibration and phonon-assisted tunnelling between the 2 E and 4 T 2 states of Cr3+ ion.
