The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative peace prices https://gtr-ktpcrystal20739.blogcudinti.com/34929900/getting-my-er-yb-yab-crystal-to-work
