The nonradiative changeover rates Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation charges https://dkdp-switch-crystal53175.blogspothub.com/32419288/er-yb-yab-crystal-can-be-fun-for-anyone
