The nonradiative changeover fees Keep to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure rates is https://er-yb-yab-crystal52849.vblogetin.com/38990959/5-easy-facts-about-er-yb-yab-crystal-described
