We present evidence for relatively large changes in the electro-optical properties of a polymer-dispersed liquid crystal (PDLC) due to inclusion of small concentrations of 14 nm diameter Au-nanoparticles (NPs). We observe that NPs lower switch-on electric field, increase optical transmission at certain voltages, and influence the frequency response of the PDLC.
