    This study reported the photoluminescence (PL) of nematic liquid crystal (LC) doped with gold nanoparticles (AuNPs). Our results demonstrated PL emission intensity of MBBA LC is improved with doping AuNPs, and the improvement of PL intensity increased with elevating concentration of AuNPs. As well as, the emission peak is changed due to presence of AuNPs. It was showed PL emission peak of LC has been shifted towards longer wavelength by 78nm in presence of 0.1 AuNPs. A small amount of AuNPs can be improved the PL intensity.This study reported the photoluminescence (PL) of nematic liquid crystal (LC) doped with gold nanoparticles (AuNPs).

    Gold nanoparticles (AuNPs) have been prepared for doping liquid crystal (LC) with different concentrations to study linear and nonlinear optical properties utilizing UV spectrum and Z scan technique, respectively. Z scan methods are performed by He-Ne laser at 632.8 Nanometer wavelength. It is observed that the samples can absorb in the UVA range (280-400 nm). Pure LC has high absorbance and the peak of absorbance decreases when the concentration of AuNPS increases due to the AuNPs. The nonlinear optical (NLO) properties of LC were improved by increasing the concentration of AuNPs. The presence of AuNPs changed the behavior of pure LC from two-photon absorption (TPA) to saturable absorption.

The structures of the synthesized compounds were actually determined by elementary analysis, and FT-IR, 1HNMR, 13CNMR, and mass spectroscopy. The mesomorphic properties of these mesogens were examined using differential scanning calorimetry (DSC) and optical polarizing microscopy (OPM). The synthesized molecules exhibited enantiotropic hexagonal columnar liquid crystal, which depends for the H- bond complex in a 1:3 ratio.

  • A New Series of Triazine-core Based Mesogenic Derivatives: Synthesis, Characterization and Mesomorphic Study
    Nisreen H. Karam, Nasreen R. Jber, and Ammar H. Al-Dujaili

    Molecular Crystals and Liquid Crystals, ISSN: 15421406, eISSN: 15635287, Volume: 675, Pages: 39-48, Published: 2 November 2018 Informa UK Limited
    Abstract The synthesis, characterization and mesomorphic properties of two new series of triazine-core based liquid crystals have been investigated. The amino triazine derivatives were characterized by elemental analysis, Fourier transforms infrared (FTIR), 1HNMR and mass spectroscopy. The liquid crystalline properties of these compounds were examined by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). DSC and POM confirmed nematic (N) and columnar mesophase textures of the materials. The formation of mesomorphic properties was found to be dependent on the number of methylene unit in alkoxy side chains.

  • Porous Silicon Morphology: Photo-Electrochemically Etched by Different Laser Wavelengths
    Shereen M. Faraj, Shaimaa M. Abd Al-Baqi, Nasreen R. Jber, and Johnny Fisher

    Journal of Nanotechnology in Engineering and Medicine, ISSN: 19492944, eISSN: 19492952, Published: 1 February 2015 ASME International
    Porous silicon (PS) has become the focus of attention in upgrading silicon for optoelectronics. In this work, various structures were produced depending on the formation parameters by photo-electrochemical etching (PECE) process of n- and p-type silicon wafer at different time durations (5–90 mins) and different current densities (5, 15, and 20 mA/cm2) for each set of time durations. Diode lasers of 405 nm, 473 nm, and 532 nm wavelengths, each 50 mW power, were used to illuminate the surface of the samples during the etching process. The results showed that controlled porous layers were achieved by using blue laser, giving uniform structure which can make it possible to dispense with expensive methods of patterning the silicon.

  • Effects of carbon nanotubes on the physical properties of a nematic liquid crystal N-(4′-methoxybenzylidene)-4-butylaniline
    Nasreen Raheem Jber, Alaa Adnan Rashad, and Mehdi Salih Shihab

    Journal of Molecular Structure, ISSN: 00222860, Volume: 1043, Pages: 28-36, Published: 5 July 2013 Elsevier BV
    Abstract In this work, the nematic liquid crystal (LC) N-(4′-methoxybenzylidene)-4-n-butylaniline (MBBA) was prepared and doped with different concentrations (0.025, 0.05, 0.06, 0.07, 0.08, and 0.1 wt.%) of multi-walled carbon nanotubes (CNTs) at room temperature to study the electric properties of (LC–CNTs) cell. The experimental results showed that capacitance of (LC–CNTs) cell became higher than that of pure LC cell. The dielectric permittivity is determined as a function of applied frequency (100 Hz to 100 kHz) at voltage (5 V); it is found that increasing concentration of CNTs (0.1 wt.%) led to increase in the real part dielectric constant and decrease in imaginary part for (LC–CNTs) cell compared with the pure liquid crystal. Also conductivity of (LC–CNTs) cell was increased with increasing concentration of CNTs more than 0.05 wt.%. Theoretical study was carried out by using PM3 method for stable geometries of a nematic liquid crystal molecule of MBBA assembled parallel on a molecule of single-walled carbon nanotube (CNT). The result showed that the interaction caused by π,π-stacking between MBBA molecule and the wall of CNT and that may lead to formation of the local short range orientation order by LC molecules on the surface of the CNT. The binding energy of the LC molecule on the CNT wall was within the typical van der Waals interaction.
