The nonradiative changeover charges Keep to the formulation WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy hole. The nonradiative transition premiums of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure fees is intricate from th
