The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs https://erybyabcrystal96173.blogs-service.com/64028755/rumored-buzz-on-er-yb-yab-crystal
