The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://hatshepsutr381gko8.fliplife-wiki.com/user
