The nonradiative transition premiums follow the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace prices is sophistic
