The nonradiative transition premiums follow the components WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace prices is challenging https://reidnoonj.dailyblogzz.com/35388744/the-best-side-of-er-yb-yab-crystal
