The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the energy gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest premiums is https://erybyabcrystal93008.blogspothub.com/32334177/helping-the-others-realize-the-advantages-of-er-yb-yab-crystal
