| dc.description | The luminescence spectra of Pr<sup>3+</sup> in Na<sub>5</sub>La(MO<sub>4</sub>)<sub>4</sub> (M=Mo, W) at 4.2 K have been investigated. One- and two-phonon vibronic replicas are observed in the excitation spectra, suggesting that the contribution of the Delta process (Franck-Condon replicas) to the vibronic coupling strength of Pr<sup>3+</sup> is significant. The transition probability A<sub>vib</sub> for the vibronic lines in the <sup>3</sup>H<sub>4</sub> to <sup>3</sup>P<sub>0</sub> excitation spectra of Pr<sup>3+</sup> in several isostructural (scheelite-like) host lattices scales with the transition probability for the zero-phonon line. This is consistent with a vibronic coupling in which the Delta process dominates. The transition probabilities A<sub>vib</sub> for the <sup>3</sup>H<sub>4</sub> to <sup>3</sup>P<sub>2</sub> excitation and the <sup>3</sup>P<sub>0</sub> to <sup>3</sup>F<sub>2</sub> emission transitions, and the vibronic spectra of Pr<sup>3+</sup> in Na<sub>5</sub>La(MO<sub>4</sub>)<sub>4</sub> give additional support for this conclusion. |
