THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace fees is difficult bec
