The nonradiative changeover charges Keep to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest rates is https://lennye681bzw1.wikiconversation.com/user
