5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover charges follow the formulation WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the energy hole. The nonradiative changeover prices of Er3+ show temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest fees is difficult by the existence
