Sushynskyi O. Development of items of electronic equipment based on modified active nanoscale impurity cholesteric liquid crystals

Thesis is devoted to development of electronic device elements on the base of cholesteric liquid crystals (CLC) modified by active nanoscale particles (ANSP). The paper studies spetkrylnyh, nonlinear and electro-optical properties as pure and as induced cholesteric liquid crystals modified by nanoscale particles. Pattern in changing step supramolecular helical structure modified by NRCH in depends of the mechanism of induction of helix structure of CLC matrix. The study of intercalation of nanocomposites on the base of on CLC modified by ANSP in porous materials, such as polisteren, alumina and silica oxides are carried out. It was founded patterns vpyvu the influence of gas molecules on changes in spectral characteristics of the synthesized nanocomposites. It was founded the two-stage process of the changing in the optical transmission spectra of nanocomposites on the base of on CLC modified by ANSP. The study of nonlinear phenomena in gold nanorods by means of z-techniques and low-intensity He-Ne laser are carried out. The numbers of electronic devices structures are designed. The structures of primary transducers for optical gas sensor are made, witch operation work based on changing of supramolecular pitch of CLC helical structure under the influence of gas molecules on active nanoscale particles. It was obtained the solid state structures for primary transducers for optical gas sensors by means of intercalation method of CLC molecules modified by ANSP in porous structures (polisteren, aluminum and silicon oxides). The structure of active elements of DFB-lasers at CLC modified by ANSP, which increased the spectral density of photonic states in these structures and reduce the threshold and achieve tuning wavelength lasing. The structure of the active color pixel element for LCD with organic light emitting diode pumping was proposed.
