The nonradiative changeover premiums follow the system WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated https://ralstonr146oom7.newbigblog.com/profile
