Used as a precursor in metal-organic chemical vapor deposition (MOCVD) for growing yttrium-based thin films, especially in the fabrication of superconducting materials like YBCO (yttrium barium copper oxide) on substrates. These films are critical in high-temperature superconductor applications such as sensitive magnetic field detectors, power transmission cables, and microwave devices. Its high volatility and thermal stability make it suitable for precise, controlled deposition processes. Also employed in the synthesis of yttrium-doped materials for phosphors and optical coatings where uniform dispersion of yttrium is required.
