The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electrical power hole. The nonradiative changeover prices of Er3+ show temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is https://er-yb-yab-crystal53951.blogminds.com/the-definitive-guide-to-er-yb-yab-crystal-31878983
