The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation https://dominickzdptq.izrablog.com/33637840/er-yb-yab-crystal-an-overview
