ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Strength gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace charges is complicated w
