Used primarily in research and specialized optical materials, this compound serves as a precursor for synthesizing other gadolinium-containing compounds. It finds application in the development of scintillation detectors due to its ability to emit light when exposed to radiation, useful in nuclear imaging and radiation monitoring. Also employed in the preparation of doped crystals for solid-state lasers and luminescent devices, where its paramagnetic properties enhance performance. Limited use in commercial applications due to sensitivity to moisture and handling requirements.
