The nonradiative changeover charges Keep to the formulation WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Electrical power hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure https://er-yb-yab-crystal52839.like-blogs.com/33091137/the-5-second-trick-for-er-yb-yab-crystal
