Used as a host material in phosphors for LED lighting and display technologies due to its excellent luminescent properties. Commonly doped with rare earth elements like europium or terbium to produce red or green emission. Applied in solid-state lasers and scintillators for radiation detection because of its thermal stability and efficient light output. Also utilized in thin-film coatings and electronic substrates where high dielectric strength and compatibility with semiconductor materials are required. Shows promise in high-temperature applications such as thermal barrier coatings in aerospace and turbine components.
