The 2-Minute Rule for Er:Yb:YAB Crystal
The nonradiative transition premiums Adhere to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated f
