The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest https://erybyabcrystal96284.popup-blog.com/32403359/er-yb-yab-crystal-options
