The nonradiative transition charges Stick to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition prices of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices https://erybyabcrystal85172.blog-ezine.com/33406407/the-definitive-guide-to-er-yb-yab-crystal
