The nonradiative changeover charges Stick to the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electrical power hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest https://er-yb-yab-crystal53940.blog5star.com/33644069/the-basic-principles-of-er-yb-yab-crystal
