The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://er-yb-yab-crystal51739.newsbloger.com/33705799/er-yb-yab-crystal-an-overview
