Used as a precursor in the synthesis of praseodymium-based catalysts for organic transformations and oxidation reactions. Employed in the preparation of specialty glasses and ceramics to impart yellow-green color, improve refractive index, and provide UV protection. Applied in the production of phosphors for display technologies and lighting. Utilized in research for doping in laser materials and solid-state devices. Also used in the fabrication of thin films for optical coatings and electronic components, as well as in art and decorative applications for high-temperature resistant pigments.
