The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate https://er-yb-yab-crystal42962.blogsuperapp.com/35394735/er-yb-yab-crystal-an-overview
