NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition fees Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because of
