The nonradiative changeover fees Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://caidentqmfx.spintheblog.com/35215432/the-5-second-trick-for-er-yb-yab-crystal
