The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest costs is https://erybyabcrystal18416.dm-blog.com/33139103/5-essential-elements-for-er-yb-yab-crystal
