The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace charges https://erybyabcrystal20627.dgbloggers.com/33557060/a-secret-weapon-for-er-yb-yab-crystal
