The nonradiative transition costs follow the formulation WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electrical power hole. The nonradiative changeover rates of Er3+ show temperature dependence according to the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure costs is https://douglasd691dbz2.ourabilitywiki.com/user
