Synthesis of Pr³⁺-doped WO₃ particles: correlation between photoluminescent and photocatalytic properties.

ABSTRACT: The WO₃ and WO₃:Pr³⁺ particles were successfully synthesized by the co-precipitation method. The XRD analysis with Rietveld refinement revealed the formation of a monoclinic phase for WO₃ and for doped samples, this result was later confirmed by Raman spectroscopy studies. The presence of Pr³⁺ in the WO₃ crystalline lattice induced structural and optical changes in the particles, increasing the crystallite size, distorting the clusters (shortening of the W-O bonds), favoring the crystallinity and changing the optical gap. The predominant morphology of the particles of WO₃ and WO₃:Pr³⁺ obtained was nanocubes constituted by the superposition of plates of nanometric thicknesses. The photolumines
