The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://erybyabcrystal17395.howeweb.com/33897894/the-5-second-trick-for-er-yb-yab-crystal
