ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Stick to the formulation WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Strength gap. The nonradiative transition rates of Er3+ show temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticat
