The nonradiative changeover costs Stick to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://erybyabcrystal07395.blogsumer.com/32385051/the-best-side-of-er-yb-yab-crystal
