Herein, three photorefractive (PR) composite films were fabricated. They consist of poly (N-
vinycarbazole)(PVK, 33 wt%), 2, 5-dimethyl-(4-p-nitrophenylazo) anisole (DMNPAA, 50 …

Facile photorefractive (PR) composite films were prepared. As evidence of PR effect of the
PR composite films, two-beam coupling (TBC) experiment were carried out at 633 nm …

We describe a PVK-based photorefractive polymer composite doped with disperse red 1,
poly-butylacrylate and TNF. Using the two-beam coupling experiment, we investigate its …

Photoconductivity and birefringence are two important factors that affect performances of
photorefractive devices. Here, the optical properties of this composite based on copoly [6 …

A novel electro-optical chromophore, 1-hexyloxyl-2, 5-dimethyl-4-(4′-nitrophenylazo)
benzene (HDMNPAB), is reported which is suitable for the performance of the …

Abstract Poly [N‐(2‐ethylhexyl)‐3‐vinylcarbazole has been synthesized by radical
polymerization from N‐(2‐ethylhexyl) 3‐vinyl‐carbazole. The 50‐μm thick photorefractive …

We developed new composite polymer system with monolithic azo dye substances (NACzE
and NACzH) and high optical quality polymer hosts (PMMA and PEMA), and obtained quite …

We report an organic/inorganic polymer composite based on the chemically hybridized
photoconductor CdS–PVK nanocomposite doped with a new second-order optically …

We present the enhanced photorefractive performance of high molecular weight poly (N‐
vinyl carbazole)(PVCz)‐based composites. Higher diffraction efficiency with faster speed of …

The organic photorefractive (PR) materials and devices have attracted much interest due to
the wide potential applications. In this talk, we report the recent study on PR materials and …
