The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure costs https://er-yb-yab-crystal52840.shoutmyblog.com/32329128/5-simple-techniques-for-er-yb-yab-crystal
