The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), exactly 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 principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://erybyabcrystal85173.wssblogs.com/33123796/er-yb-yab-crystal-an-overview
