The nonradiative changeover costs Adhere to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://er-yb-yab-crystal01739.goabroadblog.com/32404363/the-best-side-of-er-yb-yab-crystal
