Abstract

The lifetimes of the R-lines from the ²E level and the broad bands from the ⁴T₂ level of Cr³⁺ ions in various garnet crystals vary with the energy separation between the ²E and ⁴T₂ 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 ²E and ⁴T₂ states of Cr³⁺ ion.
