Effect of gold nano-particles on switch-on voltage and relaxation frequency of nematic liquid crystal cell

Effect of gold nano-particles on switch-on voltage and relaxation frequency of nematic liquid crystal cell

We report the observation of large changes in the electro-optical properties of nematic liquid crystal (NLC) due to inclusion of small concentration of 10 nm diameter gold nanoparticles (GNPs). It is observed that GNPs lower switch-on voltage and also lower the relaxation frequency with applied vol...
