The nonradiative transition rates Stick to the formula WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Strength gap. The nonradiative transition prices of Er3+ exhibit temperature dependence according to the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace rates is complex https://martint146ppm7.wikicorrespondent.com/user
