ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the energy hole. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated fro
