Abstract (sommario):

Electrooptical properties of conventional Polymer-Dispersed Liquid Crystals (PDLC) composites were compared in visual and near-IR ranges for the electrically-induced light transmission effect. It was confirmed that the most important for the optical contrast value is the matching of refractive indices of the polymer matrix and dispersed droplets of liquid crystal, as well as matching droplet size and wavelength of incident radiation. The optimization of electrooptical parameters of such materials needs new liquid-crystalline mixtures dedicated for near-IR range. The studied effect can be applied for manufacturing window glasses with electrically adjusted transmission of infrared radiation. Keywords: material science, liquid-crystalline composites, PDLC, electrooptics, infrared

Abstract (sommario):

Research on the characteristics of colloidal silver solutions based on changes in concentration and electric field using electrooptic devices has been carried out. The purposes of this study was to determine the characteristic of colloidal silver solution based on variations in concentration and electrooptic effects. Electrooptics work based on changes in the polarization angle of the sample. The sample used is a colloidal silver solution with various concentrations. The colloidal silver solution was obtained by laser ablation method and then dissolved in aquabidest. The light source used is a laser pointer with = 532 nm. The electric field applied to the sample is 0-9 kV. The results showed that colloidal silver solution at an angle of 0º showed active plasmon resonance at the peak of polarization with concentrations of 1.9 ppm, 2.28 ppm, and 3.8 ppm. An angle of 90º also shows active plasmon resonance at the peak of polarization with a concentration of 3.8 ppm. From the results, it can be concluded that the characteristics of colloidal silver solution on change in the polarization angle due to an electric field show non-linier properties with increasing concentration.

Abstract (sommario):

Lead zirconium titanates(PZT) are ferroelectric materials of considerable current interest because their potential for applications in memory devices and electrooptics has drawn the attention of industry. The performance of the devices made of PZT largely depends on the behaviors of ferroelectric domains and domain boundaries. TEM has been proved to be a very powerful tool in the study of ferroelectric domains and domain boundaries in ferroelectric materials. It is suggested that around the domain boundaries in BaTiO3 there is a distribution of lattice distortion and strain field. However, few references have been found on the study of ferroelectric domains and domain boundaries in PZT materials by TEM.

Abstract (sommario):

Crystals of [(CH2OH)3CNH3]H2AsO4 have been grown, and X-ray diffraction analysis has shown them to be monoclinic, with space group P21. A three-dimensional network of hydrogen bonds of the type O-H. . . O and N-H. . . O forms strong cation-cation and cation-anion linkages. Stabilizing the structure, they create favourable conditions in the crystal to be polar. The temperature dependent behaviour of the dielectric permittivity, measured along three crystal axes in the range 100 - 300 K, did not show any evidence for a phase transition, while the pyroelectric properties of the crystal confirmed the lack of a centre of symmetry. These polar features locate [(CH2OH)3CNH3]H2AsO4 among the materials applicable to electrooptics and for the second harmonic generation.
