The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate https://epicurusq036qse5.wikienlightenment.com/user
