The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative transition rates of Er3+ show temperature dependence in step with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative leisure premiums https://erybyabcrystal17394.dailyblogzz.com/35385105/er-yb-yab-crystal-can-be-fun-for-anyone
