摘要：

Optical-absorption and laser-selective-excitation spectroscopy have been used to investigate the electronic energy level structures of the actinide ion Cm3+ and the lanthanide ion Gd3+ in host crystals of LuPO4. Crystal-field levels have been determined up to 35 000 and 37 000 cm(-1), respectively, for the principal D-2d symmetry substitutional site. These have been analyzed in terms of a parametric Hamiltonian and the two systems compared. High-resolution fluorescence spectroscopy was used to resolve the ground-term splittings of Cm3+ and these are compared to the zero-field splittings measured in a previous EPR investigation. Some weaker fluorescence features also were observed, which are attributed to minor Cm3+ sites in the host lattice. Two-photon excitation was observed to the P-6(5/2) and P-6(7/2) multiplets of Gd3+.
