Absorption spectra of Pr3+ and Nd3+ diluted in LuPO4 and YPO4 crystals have been measured from 4000 to 30 000 cm−1, at liquid He and N2 temperatures. Fluorescence was observed for Pr3+ and Nd3+ in YPO4, and Zeeman spectra were obtained in the visible region. The transitions were assigned and fit to a semiempirical Hamiltonian with adjustable parameters via a least squares procedure. Satisfactory fits and reasonable agreement between calculated and measured g values were obtained.

“…Figure 9 shows this relationship; for comparison, corresponding linear dependences are shown for the known zero field splittings of Gd 3+ in zircons [18,26] and scheelites [21]. The lattice constants were available in the literature (zircon structure silicates [28][29][30], germanates [31] and phosphates [32], scheelite structure germanates [31,33], molybdates [34,35] and tungstates [35,36]).…”

In memoriam Professor Gerhard LehmannElectron paramagnetic resonance spectra of tetravalent terbium ions have been observed in host crystals of ZrSi0 4 , HfSi0 4 , ThSi0 4 , ThGe0 4 (zircon structure) and ZrGe0 4 , HfGe0 4 (scheelite structure) at X band and Q band and various temperatures. The spin Hamiltonian parameters have been determined from the rotational diagrams; the zero field splittings turned out to be extremely large, so that complex spectra far from the strong magnetic field limit had to be analyzed. In all the compounds Tb 4+ substitutes for the tetragonal metal lattice sites. The incorporation of terbium, the origin of the large second-order parameters and comparisons with the spectra of trivalent gadolinium in similar systems are discussed.

The absorption spectra of Er3+ diluted in LuPO4 and HfSiO4 crystals have been measured from 6000 to 28 000 cm−1 at liquid He and N2 temperatures. Zeeman spectra were obtained in the visible region. The transitions were assigned and fitted to a semiempirical Hamiltonian with ten adjustable parameters. Satisfactory fits were obtained including reasonable agreement between calculated and measured g values.
