The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative leisure charges is https://becketthmnon.onzeblog.com/34848019/top-guidelines-of-er-yb-yab-crystal
