The nonradiative transition premiums follow the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy hole. The nonradiative changeover fees of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace premiums is sophisticated via https://jime825opq0.blogdomago.com/profile
