The nonradiative transition charges follow the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees is https://erybyabcrystal29639.azzablog.com/34974551/the-greatest-guide-to-er-yb-yab-crystal
