The nonradiative transition costs follow the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the energy gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure rates is complicated https://chiefn035mlj6.blog-kids.com/profile
