The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Strength gap. The nonradiative transition fees of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://gtr-ktpcrystal30633.ttblogs.com/14471316/a-simple-key-for-er-yb-yab-crystal-unveiled
