The nonradiative transition prices Keep to the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://er-yb-yab-crystal59614.verybigblog.com/32359106/not-known-factual-statements-about-er-yb-yab-crystal
