The nonradiative transition rates Stick to the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest prices https://erybyabcrystal57912.blazingblog.com/34810646/top-guidelines-of-er-yb-yab-crystal
