Bidirectional molecular reorientation induced by localized surface plasmon

Incorporation of luminescent semiconductor nanoparticles into liquid crystal matrix

“…Doping of liquid crystal with these nanoparticles at this content have not improved the photo-electrorefractive effect. Possible mechanisms of potential effect could be due photoheating, causing decrease of birefringence [27] or change of electronic oscillations inside the nanoparticle induced by light, causing change of local electronic potential distribution influencing the alignment of the molecules in the neighborhood [28]. One can expect, that photo-electrorefractive effect may be enhanced in such system, when transfer of electronic potential from nanoparticle through the ligands of the nanoparticles will be provided, causing the interaction with liquid crystal molecules observable.…”
