The nonradiative changeover rates Stick to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative peace premiums is https://jaidenjkhea.blogsvirals.com/32269633/er-yb-yab-crystal-an-overview
