The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Vitality gap. The nonradiative transition fees of Er3+ show temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest charges https://hilairel925mmj6.wikipowell.com/user
