The nonradiative changeover rates Keep to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure charges is https://erybyabcrystal86395.bleepblogs.com/33646476/getting-my-er-yb-yab-crystal-to-work
