The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), where p is the amount of phonons matching the energy hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace charges is challenging https://manuelhjifc.blogadvize.com/40601631/the-best-side-of-er-yb-yab-crystal
