摘要

Sodium praseodymium orthophosphate Na₃Pr(PO₄)₂ was prepared using high temperature molten salt method and structurally characterized by single-crystal X-ray diffraction (SC-XRD) analysis. Its structure can be modeled as a four-dimensional (4D) commensurately modulated structure with orthorhombic superspace group Pca2₁(0 1/3 0)000 or as a conventional 3D superstructure description. The structure contains PrO₈, NaO₆, NaO₇ and PO₄ polyhedra, which are in six types of linear array along the a-axis. Furthermore, the excitation and emission spectra, decay time and Commission International de l’Éclairage (CIE) chromaticity index of Na₃Pr(PO₄)₂ were studied. Under blue light excitation (468 nm), the powdered Na₃Pr(PO₄)₂ calcined at 1200 °C shows the strongest red emission at around 610 nm, which originates from the ³P₀→³H₆ and ¹D₂→³H₄ transformations of Pr³⁺ ion.
