The nonradiative transition costs Keep to the components WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation charges https://heinrichm914jih5.blog-ezine.com/profile
