The influence of the surface nanostructured relief on the near IR-spectral shift and on the structural properties of the nematic liquid crystal (NLC) materials doped with nanoparticles from lanthanide group has been considered. The relief mentioned above has been made on the interface between glass substrate with ITO-coatings and the LC mesophase. The specific feature of this relief is based on the applying of the contactless laser deposition technique and on the its modification by using surface electromagnetic waves (SEW) or carbon nanotubes (CNTs) treated with SEW. The modified relief permits to orient LC molecules without direct polymer orienting layers and can be used as conducting layer too. The features mentioned above lead to decrease drastically the resistivity and the bias voltage as well as that permits to increase the transparency and reveal the near IR-shift in the spectral characteristics of the lanthanide-doped LC mesophase.

It is well known that different technical methods and physical-chemical approaches can be used to improve the basic properties of optical materials operated in the UV-VIS-IR spectral range. Laser-based equipment and a nanotechnology approach can be jointly applied with good advantage. In this paper, the advantage of the laser-oriented deposition technique is discussed. Promising nanoobjects based on carbon nanotubes and LiF structures were considered, and their spectral, mechanical and wetting properties were evaluated. It was found the modification of the LiF with the carbon nanotubes improves the optical properties of the former. The quantum chemical simulations confirmed the experimental results obtained. Besides, the changes in the properties of the other classical materials (such as KCl, KBr, MgF2, etc) were comparatively shown.

Modifications of bulk and surface properties of materials covered with nanoobjects such as: fullerenes, nanotubes, quantum dots, shungites, graphenes, etc., were studied. Improved photorefractive, photoconductive, mechanical and spectral properties were observed for the optical materials operating in the UV-VIS-IR spectral ranges. A wide area of possible applications of these materials in optoelectronics, laser techniques and solar energy conversion is proposed and discussed.

Одной из проблем сохранения функциональных свойств жидкокристаллических (ЖК) электрооптических пространственно-временных модуляторов света, а также ЖК-ячеек и аналогов дисплейных элементов, является наличие качественных проводящих контактов, выдерживающих определённые уровни прикладываемых напряжений и световых нагрузок. В настоящей работе проведено исследование механической, лазерной прочности, спектральных и рефрактивных параметров ITO-проводящих слоев, структурированных углеродными нанотрубками (УНТ), осаждаемых на ITO-покрытие лазерным бесконтактным методом при варьировании напряженности электрического поля. Приведены как расчетные, так и экспериментальные альтернативные аргументы в пользу применения одностенных УНТ, а также сделаны выводы о преимуществе использования структурированных ITO в качестве как проводника, так и ориентанта, для ориентирования ЖК-молекул. Ключевые слова: жидкие кристаллы, граница раздела сред, рельеф поверхности, ITO-покрытие, углеродные нанотрубки, лазерный метод осаждения, прочность, глубина проникновения, спектр, поверхностная электромагнитная волна.
