Photorefractive Inorganic-Organic Polymer-Dispersed Liquid-Crystal Nanocomposite Photosensitized with Cadmium Sulfide Quantum Dots
We report on a new photorefractive medium consisting of a hole-transporting polymer composite matrix, electro-optically active nanodroplets of liquid crystals, and cadmium sulfide quantum dots as photosensitizers. This medium exhibits greater than 90% internal diffraction efficiency and a net two-beam coupling gain of 22.5 cm-1 with a response time of < 1 min. Data on optical transmission are also presented. © 2002 Optical Society of America.
