Used as a precursor in the synthesis of yttrium-based materials such as yttrium oxide, which is essential in producing phosphors for LED lighting and display technologies. Commonly employed in sol-gel processes to fabricate thin films and nanomaterials due to its high solubility and reactivity. Plays a role in catalyst preparation for organic reactions and in doping ceramics to enhance thermal and electrical properties. Also utilized in research for developing luminescent compounds and in the electronics industry for making yttrium iron garnet (YIG) components.
