WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative transition premiums of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest fees is difficult from the ex
