The nonradiative transition fees Adhere to the system WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence in keeping with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure rates https://erybyabcrystal85172.daneblogger.com/32294665/rumored-buzz-on-er-yb-yab-crystal
