The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation premiums is https://erybyabcrystal96284.blogsvila.com/33422844/er-yb-yab-crystal-can-be-fun-for-anyone
