Donor-acceptor systems are likewise effective (Scheme 10.9) [42] and still more are quantum dots (nanomaterials small enough to exhibit quantum properties) [43, 44]. A hybrid organic/inorganic architecture has been demonstrated to be able to collect high-energy photons in pentacene, where these are transformed into low-energy photons, while at the same time low-energy photons are collected [45] (Scheme 10.10). 

Inorganic organic hybrid polymer dispersed liquid crystalline nanocomposites are reported as suitable candidate for fahricatirHi of photorefractive medium. Winiarz et al. reported one such photorefractive medium which consists of hole transporting polymer composite matrix, electro-opticaUy active nanodroplets of liquid crystal and Cadmium sulphide quantum dots as photosentizers (Winiarz and Prasad 2002). They employed poly(methylmethacrylate) (PMMA) as polymer matrix, N-ethylcarbazole (ECZ) as hole transporting medium and commercial nematic liquid crystal mixture TL 202 for fabrication of the photorefractive medium with Cadmium sulphide as photosentizer. The reported medium exhibits more than 90 % internal diffraction efficiency which is relatively high compared with other PDLC photorefractive medium.
