Latest Patents
Dan Qu holds a patent for "High refractive index crystalline colloidal arrays materials and a process for making the same." This patent discloses a new composite material and a process for synthesizing highly charged, highly monodisperse core-shell particles with high refractive index cores. The core particles can be highly monodisperse zinc sulfide (ZnS) particles, while the shell can consist of highly charged polyelectrolytes. The resulting crystalline colloidal arrays (CCAs) are charge-stabilized photonic crystals that exhibit distinctive first and second order Bragg diffraction peaks. These peaks vary over a wide spectral region from UV through visible to IR, showcasing unusually strong intensity and broad bandwidth due to the high index of refraction. The high refractive index particles developed by Qu are useful in applications such as optical filters, optical coatings, cosmetics, and photonic crystal sensors and devices.
