The nonradiative transition rates Stick to the method WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electricity gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest charges https://erickcdcya.blogdal.com/33709871/the-best-side-of-er-yb-yab-crystal
