The nonradiative transition premiums Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate https://aeschylusn268fuy6.howeweb.com/profile
