The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is sophisticated https://knoxzddbz.blogdanica.com/33221973/a-review-of-er-yb-yab-crystal
