Electro-optic and dielectric studies of silica nanoparticle doped ferroelectric liquid crystal in SmC* phase

Dielectric and Electro-Optical Properties of Ceramic Nanoparticles Doped Liquid Crystals

“…Choudhary et al presented the results based on the electro optic and dielectric properties of silica nanoparticles doped ferroelectric liquid crystal in SmC* phase [74]. Switching time, spontaneous polarization and rotational viscosity decreased with increase in silica concentration.…”

Effects of silver nanoparticles doping on morphology and luminescence behaviour of ferroelectric liquid crystals Langmuir–Blodgett films

“…[5][6][7][8][9][10] With low-concentration doping of nanoparticles, the electric and dielectric properties of ferroelectric liquid crystalline materials have been improved. [11,12] Doping of nano-objects in FLC matrix has their effect on switching time, spontaneous polarisation and rotational viscosity and photoluminescence intensity. [13][14][15][16][17] Silver nanoparticles in nematic LC have improved its dielectric behaviour [18][19][20] -the nematic LC shows enhancement in luminescence [21] and variation in electro-optical parameters.…”

Electro-optic, dielectric and optical studies of NiFe2O4-ferroelectric liquid crystal: a soft magnetoelectric material

“…[5][6][7][8][9][10] Dispersion of a small amount of numerous types of NPs, e.g. carbon nanotubes (single-/ multi-walled), [11] ferroelectric (Sn 2 P 6 S 6 , BaTiO 3 ), [9,12] metal (Au, Ag, Cu, Si), oxides (MgO, SiO 2 , Y 2 O 3 , Ag, Pd, CdS, Au, Pt), [13][14][15][16] quantum dots (CdSe, CdTe, ZnO, ZnS), [17][18][19] graphene, and NPs in nematic LCs and FLCs, has been considered by different research groups. Doping of such NPs does not induce much distortions in the phases of LCs; however it modifies and improves the response time, photoluminance properties, threshold voltage and contrast of LC devices, which may be beneficial in the designing and fabrication of modern and advanced devices.…”
