The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest rates is intricate from the https://er-yb-yab-crystal74172.blog-ezine.com/33301293/er-yb-yab-crystal-an-overview
