UV stable high-refractive index nanocomposites for extended reality (XR)

Nanoparticles such as titanium dioxide (TiO2) with high refractive index values of 2.0 in the visible light spectrum are increasingly being sought after for applications in XR waveguide designs for improvements in field of view (FOV). Pixelligent's PixNIL® formulations with PixClear® TiO₂ nanocrystals can create diffractive optical elements and planarized films with refractive index values of up to 2.0 at 520 nm. With the introduction of high refractive index formulations with PixCor™, a new line of nanocrystals using Pixelligent's proprietary "Core-Shell" technology, we offer significantly improved resistance to near-UV and UVA light exposures in nanoimprintable formulations. The films containing PixCor™ technology maintain very high transparency and low haze in the visible light spectrum and demonstrate high refractive index of 1.9 at 520 nm, and low absorbance, all while maintaining nanoimprintability at commercial scale.
