✦ Synopsis

Photoelectric and photorefractive properties at 1064 nm and 1550 nm and also nonlinear optical and electron-transport characteristics were investigated in polyvinylcarbazole (PVK) and aromatic polyimide (API) layers containing closed non-oxidized and oxidized single wall (SW) and also multi-wall (MW) carbon nanotubes (CNTs). Analysis of the nonlinear optical properties for polymer composites containing 0.26 wt.% SWCNTs showed very high third-order susceptibility (1.85 Β± 0.35 β€’ 10 Γ€10 esu). This enabled us to use the unplasticized polymers having a glass transition temperature above 200 Β°C in photorefractive cells.

The optical properties of bundled nanotubes were examined for high-bit-rate telecommunication applications. The diameters of the nanotubes in the bundles were determined to be from 0.6783 to 1.5147 nm, and their chiralities were also determined using resonant vibration modes. Their crystallographic

The third-order nonlinear optical properties of polyurethane-urea/multiwalled carbon nanotube composites (PU/MWNT) films with different MWNT concentrations are investigated by the use of the Z-scan technique at a wavelength of 532 nm with a pulse duration of 8 ns. The results reveal that the nonline
