NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover prices Stick to the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace fees is sophisticated via the
