The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure rates is complex https://richardd680aya3.wikiexcerpt.com/user
