The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation fees is https://rafaeltwxwt.get-blogging.com/33694351/5-simple-techniques-for-er-yb-yab-crystal
