The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://er-yb-yab-crystal32592.verybigblog.com/32527700/the-ultimate-guide-to-er-yb-yab-crystal
