The nonradiative changeover fees follow the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is intricate through https://erybyabcrystal18395.blogaritma.com/31457256/er-yb-yab-crystal-an-overview
