The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is complex because https://er-yb-yab-crystal38370.bloggerswise.com/40533969/the-greatest-guide-to-er-yb-yab-crystal
