The nonradiative transition charges Adhere to the method WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electrical power gap. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace rates https://erybyabcrystal85173.ltfblog.com/32117847/top-guidelines-of-er-yb-yab-crystal
