The nonradiative changeover rates Adhere to the components WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Strength gap. The nonradiative transition charges of Er3+ exhibit temperature dependence according to the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation fees is https://erybyabcrystal29627.ageeksblog.com/32050248/top-guidelines-of-er-yb-yab-crystal
