Optical Behavior of Rhodamine B Dye Doped Nematic Liquid Crystal E-24

ABSTRACT The optical properties of rhodamine B dye doped nematic liquid crystal mixture E-24 have been investigated in temperature range340C to 570C. The variations in refractive indices, order parameter, birefringence of dye doped sample at different temperatures have been discussed. The results indicate that doped sample has a less refractive index and a higher order parameter as compared to the pure sample. The birefringence of the guest-host mixture is also less than that of the pure nematic E-24.
