The nonradiative transition charges Stick to the components WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Strength gap. The nonradiative transition charges of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure costs is https://erybyabcrystal94838.blogprodesign.com/54694737/5-simple-techniques-for-er-yb-yab-crystal
