The nonradiative changeover premiums Keep to the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace charges https://categ702dda2.worldblogged.com/profile
