The nonradiative transition charges Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure premiums https://dantectiuh.is-blog.com/41351688/little-known-facts-about-er-yb-yab-crystal
