Optical Spectra and Analysis of Pr(3+) in CaWO4.

Abstract

Optical absorption and fluorescence data were studied for the 4f(2) configuration of Pr(3+) in CaWO4. The absorption spectrum was recorded over the wavelength region from 0.3 to 2.5 micrometers at crystal temperatures of 25 and 85 K. The crystals were grown from a melt containing 1.0 atomic percent Pr(3+). These absorption data were correlated with reported fluorescence data to establish energy levels in all the terms, except the singlet S corresponding theoretical levels were obtained by diagonalizing a Hamiltonian containing the free-ion and crystal-field interactions in a basis of states spanning the ground configuration. A least-rms deviation of 18.3/cm between measured and calculated energy levels was obtained by varying the parameters of this Hamiltonian. Calculated g factors were also obtained for the energy degenerate doublets.
