A study on the design, morphology and electro-optical properties of polymer dispersed liquid crystal films doped with Sudan black B dye
To fabricate and use PDLC-based smart windows, electro-optical (EO) properties such as high transparency at low driving voltages, high contrast ratios (CR), and a wide viewing angle are critical. Thus, there is always a need to either develop new materials with excellent performance or to improve the existing ones. Doping materials (other than the LC and polymeric materials) such as dyes and nanomaterials, can also be used to adjust the EO properties. Sudan black B (SBB) dye and newly available LC material were doped in PDLC material in order to address such a scenario. In our investigation, we found that the doping SBB dye at a weight ratio of 1wt%and LC material with 60 wt% into NOA65 prepolymer PDLC resulted in a great performance of PDLC devices e.g. a high CR response (8.8) and high transmittance even at a low deriving voltage (5 Volt).
期刊介绍:
The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope.
Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees.
General topics covered include:
• Optical and photonic materials (inc. metamaterials)
• Plasmonics and nanophotonics
• Quantum optics (inc. quantum information)
• Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers)
• Coherence, propagation, polarization and manipulation (classical optics)
• Scattering and holography (diffractive optics)
• Optical fibres and optical communications (inc. integrated optics, amplifiers)
• Vision science and applications
• Medical and biomedical optics
• Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy)
• Imaging and Image processing
