We derive a general formula, using Fermi’s golden rule, for the multiphonon relaxation rate for a two-level system coupled off-diagonally to a bath of phonons. Our result is valid for any scalar form of the system-bath interaction potential. With our result we analyze experimental data involving the energy gap and temperature dependence of electronic relaxation rates for rare-earth ions in YAlO3. © 1996 American Institute of Physics.

    The 5D3–5D4 cross relaxation process of Tb3+ in CsCdBr3 has been evaluated by analysis of the decay curves of the 5D3 and 5D4 emission. The temperature dependence of the cross relaxation rate can be explained assuming phonon-assisted processes. The results show that the larger amount of...
