The nonradiative transition rates follow the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative relaxation rates is sophisticated because of https://abigailb603kln8.anchor-blog.com/profile
