“…The design and search of novel promising chromophores materials for the optoelectronic applications is very important for modern organic materials science engineering due to their promising parameters with respect to high-speed and broadband telecommunication technology [1][2][3][4][5][6]. For today different materials are just used for the nonlinear optical and electrooptical laser modulators [7][8][9][10][11][12][13].…”

Two principally novel chromophores A, B based on fluorene electron donor were synthesized and explored by 1 H NMR, 13 C NMR, and MS spectra. The delocalized energy levels have been estimated by UV-Vis absorption spectra. The principal innovation consists in modification by addition of amino group. The titled materials have demonstrated a high solubility in common organic solvents, good compatibility with polymers. The maximally achieved electro-optic efficiency of the poled film possessing 25 wt% of A doped in PMMA (25 wt% A/PMMA) achieved a value of 18 pm/V at wavelength 1310 nm, and 25 wt% B/PMMA possessed an electrooptical coefficient equal to 43 pm/V. This one open a perspective of their direct application in optoelectronic telecommunication devices for laser light modulation.

“…Атомы и ионы тяжелых металлов обладают относительно высокой электронной поляризуемостью. Поэтому стекла, содержащие такие атомы или ионы, также предлагаются в качестве электрооптических материалов [4,5]. Металлические наночастицы (НЧ) обладают значительно большей поляризуемостью, чем ионы тяжелых металлов, особенно в спектральном интервале, соответствующем плазмонному резонансу [6,7], который лежит в видимой или ультрафиолетовой областях спектра.…”

Computer simulation of polarizability and absorption cross-section of metal (Ag, Au, Cu and Na) nanoparticles in glass far from plasmon resonance, in spectral range of 1-1.6 μm was performed. Using the example of Ag nanoparticles it is shown that in telecommunication spectral range absorption cross-section decreases by 103 times, in comparison with plasmon resonance spectral range. At the same time the polarizability decreases only by 10 times. The comparison of nanoparticles polarizabilities for mentioned materials and different geometries was performed. The prospect of metal nanoparticles application for electro-optic glasses development is shown.
