The nonradiative transition rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging via https://walesv368tsp8.wikiconversation.com/user
