The nonradiative changeover charges Adhere to the system WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Strength gap. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure charges is https://andersonghgjm.develop-blog.com/40149618/the-greatest-guide-to-er-yb-yab-crystal
