The nonradiative changeover prices Keep to the system WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Power hole. The nonradiative transition rates of Er3+ show temperature dependence consistent with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest costs is https://zanderjqtqn.blogthisbiz.com/39849593/the-best-side-of-er-yb-yab-crystal
