Plasmonic nanoparticles enhancing blue emission from nematic liquid crystal

Plasmonic nanoparticles enhancing blue emission from nematic liquid crystal

The photoluminescence (PL) performance of 5CB (n-pentyl-n′-cyanobiphenyl) containing with various concentrations of Ag and Au nanoparticles have been investigated. The PL enhancement and quenching of 5CB are found when the concentrations of dopants are in range of 60–80 μL and 40–60 μL, respectively...
