| Abstract | We present the optimization of poly(N-vinylcarbazole) (PVCz)-based photorefractive composite films for use in a dynamic holographic imaging system. The compositions of the composite films used in this study included PVCz/4- azacycloheptylbenzylidenemalononitrile (7-DCST)/carbazoylethylpropionate (CzEPA), N- ethylcarbazole, benzyl n-butyl phthalate/ [6,6]-phenyl-C61-butyric acid methyl ester or 2,4,7- trinitro-9-fluorenone (TNF) (44/35/20/1 wt%). PVCz with molecular weights of 23 000, 100 000, 290 000, 370 000 and 810 000 g mol(-1) were used. The photorefractive polymeric composite (PPC) film (PVCz with M-w: 370 000/7-DCST/CzEPA/TNF, 44/35/20/1 wt%) was observed to be the most well- balanced for photorefractive performance. To demonstrate the practical application of these films, dynamic holographic images were reflected from a spatial light modulator. The optimized PPC film was used in the dynamic holographic imaging system, and well-balanced dynamic holographic images were obtained. The results from this study will contribute to the development of four-dimensional (4D -3D plus time) holographic displays. |
