The nonradiative transition fees Adhere to the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the energy gap. The nonradiative transition fees of Er3+ show temperature dependence in step with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges https://reiddpqol.ampblogs.com/little-known-facts-about-er-yb-yab-crystal-69874202
