The nonradiative transition premiums follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in step with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative relaxation premiums is sophisticated https://ziongjifb.prublogger.com/32430450/what-does-er-yb-yab-crystal-mean
