Used in research as a precursor for synthesizing advanced materials and metal hydrides. Shows potential in hydrogen storage applications due to its ability to absorb and release hydrogen under controlled conditions. Investigated for use in semiconductor doping and solid-state devices where yttrium-based compounds enhance performance. Also employed in specialized catalysts for organic reactions and in the development of high-temperature superconductors. Its optical properties make it suitable for certain luminescent materials and coatings in experimental settings.
