Yttrium Oxide (Y2O3) Nanopowder, < 50 nm average particle size, >99.999% purity

High purity Yttrium Oxide (Y2O3) Nanopowder for applications in biomedical imaging, solar energy processes, lithium-ion batteries, and rare-earth-doped lasers

Yttrium oxide (Y2O3), known as yttria, a highly stable rare earth heavy metal oxide. It is widely used to make phosphors Eu:Y2Owhich exhibits sharp red emissions.

Y2O3 films exhibit excellent electronic properties such as optical transparency over a broad spectral range (0.2 – 8 μm), high dielectric constant (∼ 14 – 18), high refractive index (∼ 2), large band gap (∼ 5.8 eV), low absorption (from near-UV to IR), and superior electrical break-down strength (> 3 MV/cm). Yttrium oxide, as an important phosphor material, has been widely applied in fields of white LED phosphors, solid lighting, and fluorescence sensors. Yttrium oxide nanostructures have been proven to be an excellent host matrix to rare earth ions such as Eu3+, Tb3+ and Yb3+. Yttrium oxide doped with europium (Y2O3:Eu) is a luminescent material with red-orange emission, excitation by electrons (cathodoluminescence). Y2O3:Er particles and the surface modification of these particles with double layers of PAAc (acrylic acid) as an interfacing agent and acetal-PEG-b-PAMA led to successful NIR imaging nanoparticles. With great thermal, chemical, and mechanical stabilities and its unique optoelectronic properties, yttrium oxide also finds applications in solar energy processes, lithium-ion batteries, and components for rare-earth-doped lasers.
