The nonradiative transition costs Keep to the components WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation https://holdenijhfb.blogginaway.com/33791420/the-5-second-trick-for-er-yb-yab-crystal
