Doped liquid crystals allow real time holography
The addition of buckyballs or carbon nanotubes to nematic liquid crystals changes their properties and makes them low-cost alternatives for holographic and image processing applications, according to Penn State electrical engineers. "By incorporating nanotubular and nano carbon 60 structures into liquid crystals, we make the nonlinear optical properties a million times bigger than all other existing materials," says Dr. Iam-Choon Khoo, professor of electrical engineering.
