Abstract
We have observed the enhancement in photoluminescence (PL) intensity of the antiferroelectric liquid crystals (AFLC) doped with Sodium titanate nanoparticles (NPs). The enhancement in PL intensity of AFLC strongly depends on the doping concentration of NPs. The Sodium titanate NPs were prepared such that the emission from NPs together with AFLC molecules gives enhanced PL intensity. On the other hand, smectic CA* phase of AFLC provides strong light scattering and hence incident photons get scattered to excite more NPs and give enhanced PL counts. We have also observed the shift in emission energy band of AFLC doped with NPs.
