Abstract

The crystal-field splitting of the Er[sup 3+] ground multiplet, [sup 4]I[sub 15/2], in ErPO[sub 4] is investigated by inelastic neutron scattering. Four excitations from the [Gamma][sub 7] ground state to the excited states and several transitions between the excited states have been identified. The observed transition energies and intensities are used to refine the parameters of the crystal-field potential. The calculated magnetic susceptibility, [chi](T), agrees well with experimental values from single-crystal measurements. A comparison of the neutron data with optical absorption and both nonresonance and resonance Raman scattering measurements has been made.

Excitation profiles of resonance electronic Raman scattering in ErPO/sub 4/ crystals

Journal Article Williams, G; Becker, P; Edelstein, N; ... - Phys. Rev. B: Condens. Matter; (United States)

The intensities of electronic Raman-scattering transitions between theground and excited crystal-field states of the ground/sup 4/I/sub 15/2/ multiplet of Er/sup 3 +/ incrystals ErPO/sub 4/ were measured as a function of excitationfrequency in the region of an intermediate-state resonance between the/sup 4/I/sub 15/2/ ground state and a crystal-field state ofthe /sup 4/F/sub 7/2/ multiplet. It is shown that for excitationfrequencies near the intermediate-state resonance, the observed spectra are theresult of electronic Raman scattering and are not due to absorption followed byfluorescence. No such determination could be made for direct resonanceexcitation. Enhancements of the intensities of the electronic Raman scatteringby amore »« less

Crystal-field excitations and magnetic properties of TmPO[sub 4]

Journal Article Loong, C; Soderholm, L; Abraham, M; ... - Journal of Chemical Physics; (United States)

The magnetic-excitation spectrum of TmPO[sub 4] has been studied using inelastic neutron scattering techniques. Sharp crystal-field transitions were observed in spectra obtained at 15 and 100 K, yielding new information regarding the energy-level structure of the Tm[sup 3+] ground-multiplet splitting. The data were analyzed using a Hamiltonian that included the atomic free-ion and crystal-field interactions for an [ital f][sup 12] configuration. Using the Tm free-ion parameters derived from optical spectroscopy of Tm[sup 3+] diluted in a LuPO[sub 4] host, a set of crystal-field parameters were obtained for Tm[sup 3+] in pure TmPO[sub 4].

Resonance electronic Raman scattering in erbium phosphate crystals

Journal Article Becker, P; Williams, G; Russo, R; ... - Opt. Lett.; (United States)

Resonance enhancement factors of 10 to 100 have been observed for the electronic Raman scattering transitions in crystals of pure ErPO/sub 4/ and 1% Er/sup 3 +/ diluted in LuPO/sub 4/. The resonances were excited by the 488.0-nm line of an argon-ion laser. This line is nearly coincident with the crystal-field levels of the /sup 4/F/sub 7/2/ multiplet of Er/sup 3 +/. The differences in relative intensities between the transitions in ErPO/sub 4/ and those in 1% Er/sup 3 +/ in LuPO/sub 4/ arise from shifts in the energy levels in the two systems and suggest that quantum-mechanical interference effectsmore » play an important role.« less
