The nonradiative changeover rates follow the components WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electricity hole. The nonradiative transition prices of Er3+ exhibit temperature dependence in line with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace rates is challenging https://erybyabcrystal74062.wizzardsblog.com/33098042/details-fiction-and-er-yb-yab-crystal
