The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://jaredtaayx.shotblogs.com/top-guidelines-of-er-yb-yab-crystal-47024599
