Rogers, E.G. Faculty Applied Sciences Department RST/Radiation, Science and Technology Date 2014-06-30 Abstract The electronic level schemes for divalent and trivalent lanthanide ions in rare earth (La, Gd, Y, Lu, Sc) vanadate, niobate, tantalate, and in alkaline earth (Ba, Sr, Ca, Mg) titanate, molybdate, and tungstate compounds are presented. Use is made of data from luminescence excitation and absorption spectra of lanthanide (mostly Eu3 +, Pr3 +, and Tb3 +) impurities in those compounds. By means of the chemical shift model, binding energies, relative to the vacuum energy, of electrons in the impurity levels and the host bands are obtained. It reveals clear trends in conduction band and valence band energy with changing size of the rare earth or the alkaline earth ion. The bottom of the conduction band is dominated by 3d, 4d, or 5d orbitals, and it is found that the binding energy at the conduction band bottom tends to decrease with higher orbital number.
