The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated through https://aeschylusn268fuy6.howeweb.com/profile
