The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://dominickbwlzm.tblogz.com/5-easy-facts-about-er-yb-yab-crystal-described-48254262
