Details, Fiction and Er:Yb:YAB Crystal
The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace rates is difficult through t
