The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest charges https://er-yb-yab-crystal52739.tribunablog.com/5-simple-techniques-for-er-yb-yab-crystal-47485563
