The nonradiative transition charges Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is complex https://juliusimljg.ssnblog.com/33824584/little-known-facts-about-er-yb-yab-crystal
