The nonradiative transition charges Keep to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated by the exist
