The nonradiative transition fees follow the method WNR = W (0) exp(-alphap), exactly where 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 leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation fees https://erybyabcrystal06394.bloggactivo.com/32413782/er-yb-yab-crystal-an-overview
