The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure https://sergiocdbzw.activablog.com/32460682/getting-my-er-yb-yab-crystal-to-work
