The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://er-yb-yab-crystal49482.bloginder.com/35467327/er-yb-yab-crystal-can-be-fun-for-anyone
