Abstract:We demonstrate here the effect of dispersing organosoluble carbon dots (CDs, ∼7-8 nm) on tuning the molecular alignment, dielectric and electrical properties of smectic A (SmA) and nematic (N) mesophases of a thermotropic smectogenic LC material, 4-octyl-4′-cyanobiphenyl (8CB) in a planar anchored ITO sample cell using polarized optical microscopy and dielectric spectroscopic techniques. The cross-polarised optical textures clearly show that the doping of CDs (concentration ≥0.25wt%) in planar anchored 8CB, LC… Show more
