Neater Nanocrystals

Pixelligent Technologies, which makes nano-crystal additives for the electronics and semiconductor markets, recently announced PixClear Zirconia nanocrystals.  When incorporated into existing products, these nano-additives can increase the light output and readability of touch screens and displays.  PixClear also increases the light output of products for lighting applications such as HB LEDs and OLEDs (Fig. 2).

Pixelligent was developed to address the problem of nanocrystal dispersions that can suffer from aggregation and cloudiness and are unstable and difficult to process, preventing their commercial adoption.  According to Pixelligent, its dispersions are completely clear and enable precise control over target applications’ optical, chemical, and mechanical properties.

Dispersion technology is a critical enabler for the manufacturing of very-high-quality nanocomposites used in a wide range of applications, including touch screens, OLEDs, and CMOS image sensors.  Pixelligent’s PixClear nanocrystal dispersions have been tailored to be compatible with a wide variety of monomers and polymers.  Its patent-pending synthesis and surface modification technology produces high-quality dispersions that can be incorporated into many of the most widely used polymer systems.  This enables highly transparent formulations with nanocrystal loadings in excess of 80% weight, while reaching a refractive index as high as 1.85.  Additionally, PixClear provides great flexibility for index matching of dissimilar materials.
