Journal ArticleDOI
A review on the light extraction techniques in organic electroluminescent devices
TL;DR: In this article, the authors report recent advances in light out-coupling techniques, such as, substrate modification methods, use of scattering medium, micro-lens arrays, microcavity effect, photonic crystals and nano-particles, nano-structures and surface plasmonenhanced techniques that have been implemented to enhance the external extraction efficiency of organic electro-luminescent devices.
Journal ArticleDOI
Enhanced photoluminescence in gold nanoparticles doped ferroelectric liquid crystals
TL;DR: In this paper, the photoluminescence of newly synthesized deformed helix ferroelectric liquid crystal (DHFLC) material having short pitch and high spontaneous polarization was characterized.
Journal ArticleDOI
Nonvolatile memory effect based on gold nanoparticles doped ferroelectric liquid crystal
TL;DR: In this paper, a nonvolatile memory effect based on gold nanoparticles (GNPs) doped deformed helix ferroelectric liquid crystal (DHFLC) has been observed.
Journal ArticleDOI
Laser speckle reduction by multimode optical fiber bundle with combined temporal, spatial, and angular diversity
TL;DR: Speckle contrast close to that of white light was obtained using a vibrating fiber bundle with combined temporal, spatial, and angular diversities of the illumination.
Journal ArticleDOI
Effect of carbon nanotubes on response time of ferroelectric liquid crystals
TL;DR: The fastening of the response in MWCNTs-doped DHFLC has been attributed to the decrease in rotational viscosity and increase in anchoring energy.
