The nonradiative changeover rates Adhere to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest fees is sophisticated https://franciscowyzyd.jts-blog.com/33753149/er-yb-yab-crystal-can-be-fun-for-anyone
