Functional nematic liquid crystal structures doped with nano- and bioobjects have been investigated. The self-assembling features and the photorefractive parameters of the structured liquid crystals have been comparatively studied via microscopy and laser techniques. Fullerene, quantum dots, carbon nanotubes, DNA, and erythrocytes have been considered as the effective nano- and biosensitizers of the LC mesophase. The holographic recording technique based on four-wave mixing of the laser beams has been used to investigate the laser-induced change of the refractive index in the nano- and bioobjects-doped liquid crystal cells. The special accent has been given to novel nanostructured relief with vertically aligned carbon nanotubes at the interface: solid substrate-liquid crystal mesophase. It has been shown that this nanostructured relief influences the orienting ability of the liquid crystal molecules with good advantage. As a result, it provokes the orientation of the DNA. The modified functional liquid crystal materials have been proposed as the perspective systems for both the photonics and biology as well as the medical applications.

Rod-like and sheet-like nano-particles made of desoxyribonucleic acid (DNA) fabricated by the DNA origami method (base sequence-controlled self-organized folding of DNA) are dispersed in a lyotropic chromonic liquid crystal made of an aqueous solution of disodium cromoglycate. The respective liquid crystalline nanodispersions are doped with a dichroic fluorescent dye and their orientational order parameter is studied by means of polarized fluorescence spectroscopy. The presence of the nano-particles is found to slightly reduce the orientational order parameter of the nematic mesophase. Nano-rods with a large length/width ratio tend to preserve the orientational order, while more compact stiff nano-rods and especially nano-sheets reduce the order parameter to a larger extent. In spite of the difference between the sizes of the DNA nano-particles and the rod-like columnar aggregates forming the liquid crystal, a similarity between the shapes of the former and the latter seems to be better compatible with the orientational order of the liquid crystal.

Liquid crystalline materials have been useful for display devices i.e watches, calculators, automobile dashboards, televisions, multi media projectors etc. as well as in electro tunable lasers, optical fibers and lenses. Carbon nanotube is chosen as the main experimental factor in this study as it has been observed that Carbon Nano Tube influence the existing properties of liquid crystal host and with the doping of CNT can enhance1 the properties of LC. The combination of carbon nanotube (CNT) and liquid crystal (LC) materials show considerable interest in the scientific community due to unique physical properties of CNT in liquid crystal. Dispersion of CNTs in LCs can provide us a cheap, simple, versatile and effective means of controlling nanotube orientation on macroscopic scale with no restrictions on nanotube type. LCs have the long range orientational order rendering them to be anisotropic phases. If CNTs can be well dispersed in LC matrix, they will align with their long axes along the LC director to minimize distortions of the LC director field and the free energy. In this paper, we doped liquid crystal (Cholesteryl Nonanoate) by a small amount of multiwall carbon nanotube 0.05% and 0.1% wt. We found that by adding carbon nanotube to liquid crystals the melting point of the mixture is decreased but TNI is increased. It has been also observed that with incereas in concentration of carbon nanotube into liquid crystal shows conciderable effect on LC. The prepared samples were characterized using various techniques to study structural, thermal and optical properties i.e PMS, FPSS, UV-Vis spectroscopy, FT-IR measurements, and DTA.

Boron-doped diamonds were deposited by microwave plasma chemical vapor deposition (MPCVD) method in order to investigate the influence of inlet boron concentration on the film properties. The substrate material of the specimens was pure titanium (99.9 %). Boron source was introduced into the vacuum chamber by bubbling of B2O3, acetone and methanol mixture. Samples were produced with different B2O3 concentrations in mixture (1000 ppm, 5000 ppm, and 10000 ppm). The surface morphology of the samples was observed by scanning electron microscope (SEM). X-ray diffraction was used to identify crystal structures of the films. Secondary ion mass spectroscopy was used to examine the qualitative boron contents in the films. For low B2O3 concentrations in liquid mixture (1000 ppm), the surface morphology of the film showed both micro crystalline diamond and nano crystalline diamond. For medium B2O3 concentrations in liquid mixture (5000 ppm), the surface morphology of the film was also consisted of micro crystalline diamond and nano crystalline diamond. However, the content of micro crystalline diamond decreased in comparison with low B2O3 concentration. For high B2O3 concentration in liquid mixture (10000 ppm), the surface morphology of the film was almost dominated by nano crystalline diamond. Therefore, the crystal size of boron doped diamond decreased with increasing boron concentration. From these results, it appears that boron will restrain the growth of diamond crystal during deposition.

This thesis presents the investigation of the liquid crystal (LC) - particle suspensions. Particles from nano- to micro-size, spherical to two-dimensional shapes, with different functionality are dispersed into nematic and smectic phases. The aim is to create ordered nanoparticle (NP) assemblies and thereby modify the common properties of the liquid crystal, such as dielectric anisotropy and electro-optical, revealing any interaction between particles and LC properties. It is found that for concentrations (>0.5vol%), the ferroelectric NPs have increased the sensitivity of the nematic liquid crystal to the electric field through electro-optical responses, which is seen by an enhancement in the dielectric anisotropy. This could be induced by the coupling of the electrical dipole moments in the spherical NPs with the LC director field. The electro-optical properties of the chiral smectic (SmC*) phase (tilt angle Θ, switching time τ_s and spontaneous polarisation P_s) are found to be independent of the concentration and sizes of the doped NPs. The relaxation frequency f_R of the Goldstone mode is faster in the ferroelectric NPs suspensions of 2.0vol% compared to the paraelectric NPs. In the graphene oxide (GO) - nematic LC (5CB) suspensions, the small GO sizes of mean size 560 nm are more easily dispersible than larger flakes of 2.8 micro metre mean size. As the GO concentration is increased, each of the threshold voltage and splay elastic constant dramatically increases, reaching saturation at ≈1.0wt%. The field driven switching-on time is practically not affected, while the purely elastically driven switching-off time is strongly sped-up. Interestingly, thermotropic and lyotropic LC phases are exhibited in the GO-5CB suspensions when heating the thermotropic liquid crystal into its isotropic phase. The isotropic phase of 5CB acts as a solvent for the GO particles, forming a lyotropic nematic phase with largely reduced birefringence. It is found that the nematic to isotropic phase transition is shifted toward higher temperature for the GO-5CB system compared to the BaTiO3-5CB system. Dispersions of different sizes of GO flakes are prepared in isotropic and nematic fluid media. The dielectric relaxation behaviour of GO-dispersions was examined for a wide temperature range (25-60 ℃) and frequency range (100 Hz-2 MHz). The mixtures containing GO flakes were found to exhibit varying dielectric relaxation processes, depending on the size of the flakes and the elastic properties of the dispersant fluid. The relaxation frequencies in the isotropic media were lower compared to the nematic medium. Relaxation frequencies (~10 kHz) are observed in the GO-isotropic media, which are reduced as the size of the GO flakes are decreased, are anticipated to be inherited from GO flakes. However, the fast relaxations (~100 kHz) that are observed in the nematic suspensions could imply strongly slowed down molecular relaxation modes of the nematogenic molecules. Finally, the phase diagram of lyotropic LC as a function of the lateral dimensions of the GO flakes, their concentration, geometrical confinement configuration and solvent polarity was investigated. Polarising optical microscopy was used to determine isotropic-biphasic-nematic phase evolution. The confinement volume and geometry of the sample relative to the GO size are shown to be vital to the observation of the lyotropic phase. GO LCs have the potential for a range of applications from display technologies to conductive fibres. The confinement related LC phase transition is critical toward their applications. It is also found that the stability of the LC phase is higher for the solvent of higher dielectric constant.

This thesis examines the emission properties of dye-doped liquid crystal lasers, which are of interest because they have the potential to provide compact, low threshold, tunable laser sources for applications ranging from medicine to displays. The primary aim is to provide the first detailed study of the interactions between liquid crystals (LCs) and laser dyes and to examine their effect upon the emission properties of dye-doped liquid crystal lasers. Five different dyes are examined and, in all cases, the LC host (a nematic mixture, E49) is shown to have a significant effect upon the properties of the dye, through a combination of general and specific solvent-solute interactions. Lasing is demonstrated from all five dyes in the chiral nematic (N*) mesophase. Conventional xanthene laser dyes, rhodamine 6G chloride and rhodamine B chloride, are shown to be unsuitable for N*LC lasers because their ionic nature and isotropic molecular shapes limit their solubility in LC materials. Emission is shown to occur preferentially at the long wavelength reflection band edge for small degrees of alignment of the dye in the LC host. Three elongated laser dyes (DCM, PM597 and PM580) are shown to be more compatible with E49. N*LC laser samples were made using dye concentrations in the range 0.5 wt% to 2.0 wt%. For each dye, slope efficiency (ηs) values were used to calculate relative quantum efficiency values, which decreased linearly as the concentration increased. ηs is shown to peak at a characteristic value corresponding to the balance between increasing absorbance and decreasing quantum efficiency with increasing dye concentration. The largest ηs demonstrated is 32%, which corresponds to 1.0 wt% PM597. The Eth of both PM597 and PM580 is shown to increase linearly with increasing concentration, whereas the Eth of DCM shows the opposite tendency. It is proposed that the different Eth trends indicate different quantum efficiency quenching mechanisms. Lasing was demonstrated from novel bimesogenic mixtures that showed wide temperature range blue phase I* (BP I*) mesophases. The preparation and properties of the BP I* samples are described. the nature of the laser emission is shown to depend upon the input energy used. For low inputs energies (<~ 3μJ/pulse), multimode lasing is demonstrated from the BP I* texture, whereas for high input energies (> ~ 3 μJ/pulse) random lasing is demonstrated from optically induced focal conic (N*) textures in the BP I* samples.

Using true liquid crystal templating (TLCT), a one-pot method for preparing mesoporous silicas containing metal nanoparticles is available. The method leads to well-defined systems with possible applications is selective catalysis. Using this approach, a range of metal-doped variants of hexagonal silicas (general MCM-41 family) are prepared and show surface areas >1000 m2 g–1 and pore diameters of ca 30 Å. Specifically, palladium doped-MCM-41-like silicas are prepared and are shown to be active in the selective oxidation of crotyl alcohol and the activity of the system has been investigated as a function of both metal loading and the pore length – the latter affecting mass transport and therefore rate of conversion. Templating on Pluronic P123 leads to doped SBA-15-like materials, but in contrast to the findings with low-concentration templating as commonly reported, TLCT leads to materials with surface areas of about 400 m2 g–1, which is accounted for by the absence of micropores. Catalytic results from these SBA-15 materials will also be presented.

Liquid crystals (LCs) are anisotropic fluids that exhibit numerous thermodynamically stable phases in between an isotropic liquid and a three-dimensionally ordered solid. In their simplest ordered phase, the nematic, LCs show orientational order due to molecular self assembly and at the same time maintaining fluid flow properties. In the smectic phase, they show both orientational and partial translational order characterized by a 1-d density wave. Liquid crystalline substances have been extensively studied due to their applications and as important physical models of self-assembly. The effect of the disorder and impurities on LC systems is an important and challenging problem to the fundamental understanding of phases ordering or self-assembly and continually attracts the attention of researchers. The disordered systems often display complex and rich phenomena, being the generalization of the pure (ideal) systems. Disorder can dramatically alter the physical properties of multi-component, composite systems. In particular, the effect of disorder on phase transitions is important as the disorder typically couples to the order parameter, which can be usefully described as a random local field that is conjugate to the order parameter. This is usually realized in systems with random inclusions in a phase ordering media, e.g., a colloidal dispersion of solids in a complex fluid. Another form of disorder is presented by dilution effects, which imposes instead the random breaking or weakening of intermolecular bonds or interactions responsible for the phase ordering. Exploring a good physical system representing random dilution effects in a controlled manner offers a physical probe to unresolved problems in the understanding of mesophasic order. This Dissertation presents a series of studies of dilution and different form of disorder effect on liquid crystal phase transitions. We have used high-resolution AC-calorimetry, dielectric spectroscopy as well as polarizing microscopy to characterize the effects of solvent such as hexane, acetone, decane, and nanomaterials such as multiwall carbon nanotubes and ferroelectric nanoparticles on the phase transitions of several liquid crystals. The liquid crystals of interest are: pentylcyanobiphenyl (5CB), octylcyanobiphenyl (8CB), and decylcyanobiphenyl (10CB). Studies have been carried out as a function of solvent, nanotube, and nanoparticles concentration and temperature spanning the isotropic to nematic (I-N), nematic to smectic-A (N-SmA), and isotropic to smectic-A (I-SmA) phase transitions.

The purpose of this thesis is to study effects of nano-particle-doped polyimide on liquid crystal cells, to understand influence of nano-particle-doped polyimide on liquid crystal cells of interface trapped ions. The purpose of this thesis is including that 1. When high voltage static electricity is input on liquid crystal cells, image sticking is induced by Electro-Static Discharge. 2. The ions accumulate on the interface between polyimide and LC that can induce the phenomenon interface trapped ions in LC, this will influence the optical and electric property of liquid crystal cells. In our Experimental results, we found that 1. When nano-particle-doped concentration increase, the phenomenon interface trapped charge is less that can improve the duration of image sticking caused by ESD but can not influence voltage holding ratio and residual DC. 2. There doesn’t find any relations between threshold voltage of nano-particle-doped different concentrations. 3. From optical and electric measurement we establish the model of interface trapped ions in LC.

In this study, it was found that nano-conductive powders doped in liquid crystal cells can significantly and effectively reduce the image sticking effect for the display suffering a short pulse of electro-static discharge (ESD) stress. Nano-scaled Tin-doped Indium Oxide (ITO) powders were uniformly solved in the LC cells to form a suspension solution. Both electrical and optical characteristics for the doped cells and those without intentional doping were compared. According to the measurement results from the normal voltage holding ratio (VHR), lower frequency of VHR, voltage-transmittances (V-T), enhance molecular reorientation (EMR), depressed molecular reorientation (DMR), EMR+DMR and ion density, it was shown that there is no difference between the two types of LC cells. This was shown that ion effect didn’t increase. And doping nano-ITO in LC wouldn’t have more ion effect from these measurement results. However, the capability of suffering high-voltage stress was profoundly improved for the doped cells in the ESD test. The possible reason for this finding will be discussed according to the breakdown theory of suspended particles in liquid. In order to demonstrate the possible reason, we measured induction charges of the cells by the capacitance in ESD stress. And induction charges of doping nano-ITO cells were lower than without intentional doping cells. With the results, it can be expected that the LC cells doped with conductive nano-particles would survive in worse environments while keeping their displaying characteristics unaffected. Further, a new model that conducting nanoparticles move in the liquid crystal after ESD stressing can be successfully built and explained for these results in the study.

A simple method to make a controllable liquid crystal Fresnel lens with bistable state is proposed based on a surface of polymerization and the characteristic of nanoparticles. The sample is fabricated by a homogeneous aligned substrate and a vertical aligned one of coating polymer film. However, it has low diffraction efficiency. We improve the patterned electrode type with etching electrode structure. Experimental results reveal that liquid crystal Fresnel lens which ITO etching pattern using the nanoparticles doped with liquid crystals has bistable state and high diffraction efficiency.

This thesis investigates a biphotonically controllable random lasing emission based on a dye-doped polymer-dispersed liquid crystal cell. Experimental results show that the intensity of the random lasing emission can decrease and increase with increasing the irradiated intensity of one green beam and decreasing the irradiated time of one red beam, respectively. The biphotoinc controllability of the random lasing emission can be attributable to two mechanisms: (1)After the irradiation of the green beam with increasing intensity, the concentration of the rod-like trans dyes transforming to curve cis-isomers may increase so that the LC droplets can be disturb to gradually change from nematic to isotropic phase. This may cause that the refractive indices of the LC droplet and the polymer gradually becomes match, which will induce the decrease of the diffusion constant (or scattering mean free path) of the fluorescence photons and thus the decrease of the scattering strength; in turn, the random lasing emission will decrease. (2)After turning off the green beam, the intensity of the random lasing emission can gradually recover once the cell is illuminated by one red beam with increasing irradiated time. This is because the concentration of the cis dyes transforming to the trans-isomers increases with increasing the irradiated time of the red beam via cis-trans back isomerization. The LC droplets will gradually recover from isotropic to nematic phase, and the refractive indices of the LC droplet and the polymer will gradually become mismatch. This will cause the increase of the diffusion constant of the fluorescence photons and thus the increase of the scattering strength; in turn, the intensity of the random lasing emission will gradually recover.

Terahertz (THz) photonics have been attracted much attention due to its remarkable progress [1]. Many LC devices in the visible to near-infrared range are driven using electric fields applied through transparent electrodes such as indium tin oxide (ITO) thin films. However, the inevitable absorption of ITO in THz region limits its application.[2] The alternative electrode for THz is still desired although several of approach such as nano-structure of reducing thickness of ITO have been proposed. In this work, Mg doped CuCrO2 films has been demonstrated its high transmittance in THz region. photonics. In addition, liquid crystal based terahertz (THz) phase shifter using CuCrO2:Mg as electrode was fabricated. Phase shift of around 2π at 1 THz was demonstrated. This is the first time to our best knowledge that CuCrO2:Mg can be used to fabricate THz phase shifter. The result reveal its potential for THz photonics.
