THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult be
