The nonradiative changeover costs Adhere to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is https://chriso147srq9.fare-blog.com/profile
