Core-shell technology, also known as core-shell nanoparticles, involves the synthesis of nanoparticles with a unique design consisting of a central core surrounded by a shell or coating of a different material. The core and shell materials have distinct properties, and the combination allows for enhanced functionalities and improved performance compared to individual components. For Pixelligent, our PixCor core-shell synthesized nanoparticles are composed of titania surrounded by a shell of zirconia. This was developed to get the benefits of both nanocrystals; the refractive index of titania and the UV protection of zirconia.
PixMicro™ formulations provide a versatile range of refractive indices and UV stability to meet diverse customer needs. They enable high-performance micro-imprinted microlens arrays with exceptional optical quality for waveguides, Diffractive Optical Elements (DOEs), and light guides used in Extended Reality, Display, and other Optoelectronic applications. With refractive indices from 1.65 to 1.9 and customizable viscosities, PixMicro™ products can be precisely tuned to optimize each customer's specific device and process requirements. PixMicro™ high-refractive-index, micro-imprintable products are compatible with both glass and plastic substrates, commercially available stamps, and standard manufacturing processes across a wide range of applications. High Refractive Index: Up to 1.9 for Titania formulations, Up to 1.65 for Zirconia formulations Precision Nanocrystal Control: Particle sizes ranging from 5 to 20 nm Exceptional Transparency: 95% across all visible wavelengths Ultra-Low Haze: <0.1% for superior optical clarity Tunable Film Thickness: Ranging from 3 to 15 µm Color-Neutral Clarity: b values below 1.0 PixMicro™ high-RI, micro-imprintable products deliver ultra-low haze and exceptional transparency across the full visible spectrum, offering the highest performance available on the market. These formulations are also fully compatible with industry-standard imprint stamps. PixMicro™ formulations can be applied using a wide range of processes, including spin coating and jet coating, followed by imprinting and UV curing.
