The dispersions of Pigment Red 176 nanorods in dodecane were fabricated and their elecro-optical properties have been studied. We report here on the investigation of the light transmittance as a function of applied voltage, frequency, concentration of pigment and geometry of the electrodes in the cells. The birefringence and dichroism induced by a.c. field were investigated within a high frequency range, 1 kHz to 100 kHz, and for fields up to Erms = 5 V/µm. The obtained results clearly show a great potential of dispersions of Pigment Red 176 nanoparticles for their applications in advanced optical and nonlinear optical devices.
