The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://keeganopnkg.blogoscience.com/39517077/details-fiction-and-er-yb-yab-crystal
