THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Vitality gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation premiums is challenging
