“…A detailed study of the refractive properties of the fullerene sensitized LC has permitted to propose the model connected with the increased dipole moment via increased barrier free electron pathway and the number of the delocalized charge at fullerene molecules. This model has been shown in the paper [74] and extended using other nanoparticles as promising intermolecular sensitizers in the papers [75][76][77]. It has been shown that in such sensitized organic conjugated systems the pathway of the charge transfer carrier is changed due to a fact that charge transfers from the intramolecular donor fragment of organic conjugated molecules (such as polyimide, polyaniline, pyridine, etc.)…”

“…It is connected with the change of the laser induced refractive index and, as a result, the existence of the energy losses due to diffraction on the nanostructured compounds can be included in the explanation of the OL effect. The obtained 3D picture is firstly shown in papers [77,85] and is now presented in the modified version in Fig.5. It should be mentioned that this modified version of the diffraction picture is connected with the large number of results obtained for the structured conjugated organics materials via fourwave mixing laser technique and repeated so many times.…”

Abstract. Due to important features of the organic -conjugated nano-objects-doped systems, main properties of which can compete with the basic inorganic bulk material parameters, the study of the organics is dominant. As the effective nano-objects and the intermolecular sensitizers, the following nanoparticles, such as fullerenes, nanotubes, quantum dots, reduced graphene oxide, shungites, etc. have been considered. So many applications of the organic materials doped with nanoparticles have been proposed. Among them, the optical limiting effect occupies a unique place because this process permits, on the one side, to extend the knowledge about the photorefractive features of innovative materials and, from the other side, it is predicted to develop new devices to protect human eyes and technical equipment from high energy density of the laser beam. In the current short review paper, the optical limiting effect will be considered based on the results obtained by some scientific and engineering teams. The data will be shown at the different experimental conditions: the content of the nano-sensitizers can be changed, the range of the wave lengths can be extended, and the level of the attenuation of the laser beam can be varied. It should be mentioned that the experimental wave length can be as the following: 532, 805, 1047, 1064, 1315, 1500, 2940 nm. The materials and optical element based on the structured organics will be shown under the application of the traditional optical limiting scheme and using the four-wave mixing technique to indicate energy losses via diffraction under the Raman-Nath diffraction conditions as one of the optical limiting mechanisms. The level of the attenuation of the laser beam will be shown for the organics based on polyimides, 2-cycloactyl-amine-5-nitropyridine, 2-(n-prolinol)-5-nitropyridine, liquid crystals and other materials. Some ways to form organic photonic crystals will be discussed.

“…Thus, laser-matter interaction provokes the change in polarization of the media and predicts the change in such properties as dynamic, photorefractive and photoconductive ones. To predict the change of the cubic nonlinearity  (3) , as the minimum media local volume polarizability (Kamanina, 2005, Kamanina & Uskokovic, 2008, Kamanina et al, 2012, the laser-induced change of the refractive index ni can be calculated from the diffraction efficiency  (Kamanina et al, 2015, Akhmanov & Nikitin, 1997 via realization of the Raman-Nath diffraction conditions ( -1 d) using the equation ( …”

“…The peculiarities of the growth, the mechanisms of the sensitization, and the changes of the basic physic-chemical parameters have been tested.

The main reason to use fullerenes, shungites, and quantum dots is connected with their unique energy levels and high value of electron affinity energy.…”

Because of the unique energetic, refractive and photoconductive characteristics of effective nano-objects, especially carbon nanotubes, the modification of optical properties of the organic and inorganic materials can be considered as the preferable one via the use of the nanostructuration process. Emphasis has been given to the incorporation of nanoobjects directly in the materials' body and on their surface. Under the conditions of a surface treatment of the inorganic structures, an IR-laser at the wavelength of 10.6 micrometers was used to orientate carbon nanotubes deposited in the electric field of 100-600 V×cm -1 . Dramatic spectral and mechanical parameters changes have been found. Refractive features of the nanostructured organics have been studied via applying the second harmonic of the pulsed Nd-laser at different spatial frequencies and under the nanoparticles sensitization doping such as fullerenes, carbon nanotubes, shungites, quantum dots, and graphenes. A drastically obtained laser-induced refractive index has been established. A prediction has been proposed to extend the area of the application of the systems considered.UDC Classification: 535; 538.9; 539; 544; DOI: http://dx

“…It should be said that the calculated values of nonlinear refraction n 2 and third-order nonlinear susceptibility χ [30,31,[34][35][36]. The growth of refractive coefficients correlated with the change of the photoconductive (increase of mobility of charge carriers), and it is connected with the changes in the order parameter of the studied materials and with the infrared shift of their spectral characteristics.…”

In the current chapter, the results of the optimized organic and inorganic materials features have been presented and discussed under the conditions when the material volumetric body and their surfaces have been structured. The dramatic change of the main characteristics of the inorganic matrix which surface has been modified with oriented carbon nanotubes and additionally treated by surface electromagnetic waves has been established. The transmittance and reflection spectral change, of the micro-hardness and of the wetting angle increase have been discussed due to the covalent bonding of the carbon nanotubes with the near-surface materials layers. Analytic and molecular dynamics simulations have supported the data. The essential change of the basic macro-parameters of the organic matrix, including the liquid crystal one, via their structuration with the nano-and/or bio-objects such as the fullerenes, carbon nanotubes, shungites, quantum dots, graphene oxides, DNA has been found. The spectral, photorefractive, and photoconductive characteristics modification has been discussed due to the drastic increase of the dipole moment. The laser-induced change of the refractive index has been considered as the indicator of the basic materials macro-parameters changing. It has been predicted that a scientific knowledge and the technology advances can be useful for the solar energy, display technique, for the system to absorb the gas and impurities, for the schemes with the compacted information recording as well as for the biomedicine.
