The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because https://perrye791dbz2.buyoutblog.com/profile
