Used as a dopant in scintillators for radiation detection, particularly in medical imaging and high-energy physics.

Employed in the production of fluoride glass for fiber optics due to its low phonon energy and high transparency in the ultraviolet and infrared regions.

Serves as a component in catalysts for automotive exhaust treatment and industrial chemical processes.

Utilized in the manufacturing of phosphors for lamps and display technologies.

Applied in dental and cosmetic formulations as a polishing agent for ceramics and glass due to its mild abrasive properties.

Used in research for solid-state lasers and as a precursor in the synthesis of other cerium-containing materials.
