The nonradiative transition rates Stick to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative peace costs is sophisticated https://jonathant247qon7.blue-blogs.com/profile
