The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the energy gap. The nonradiative transition prices of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is https://er-yb-yab-crystal40639.collectblogs.com/78092491/the-5-second-trick-for-er-yb-yab-crystal
