The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://nikitav157tsq9.dm-blog.com/profile
