The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is https://er-yb-yab-crystal62840.blogproducer.com/39995373/5-simple-techniques-for-er-yb-yab-crystal
