The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure costs is https://er-yb-yab-crystal81240.blogsuperapp.com/35391195/top-guidelines-of-er-yb-yab-crystal
