Used as a precursor in the synthesis of yttrium-containing materials for optical coatings and phosphors. Commonly employed in chemical vapor deposition (CVD) processes to fabricate thin films for electronic and photonic devices. Serves as a catalyst or catalyst precursor in organic transformations, particularly in reactions requiring Lewis acid conditions. Also utilized in research settings for doping ceramic materials to enhance thermal and mechanical properties. Its solubility in organic solvents makes it suitable for solution-based processing techniques in material science.
