The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is difficult because o
