摘要: Abstract Intensity data for transitions between the 4f 2 crystal-field levels of Pr 3+ in LiYF 4 are parameterized. The results consistent with an electrostatic model f-f electric dipole intensities which includes both static effects and dynamic ligand-polarization effects. They also superposition lanthanide-ligand interactions lanthanide compounds.
