THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative transition prices Keep to the formulation WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the energy gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure charges is intricate
