The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence in keeping with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation https://er-yb-yab-crystal85062.digitollblog.com/33114553/top-guidelines-of-er-yb-yab-crystal
