title: Photorefractive inorganic organic polymer-dispersed liquid-crystal nanocomposite photosensitized with cadmium sulfide quantum dots.
abstract: 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.
