The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace https://laneklkie.blogproducer.com/40047134/a-review-of-er-yb-yab-crystal
