摘要: Results obtained from studies of dye-doped polymer-stabilized cholesteric texture (PSCT) films are described. The morphology of the polymer networks and the electrooptical (EO) characteristics of the films are measured with various concentrations of methyl red (MR). The density of the polymer network is increased and the radius of the polymer network is decreased as the MR concentration in the LC/monomer mixture increases. Also, the PSCT films have a lower threshold voltage at a higher MR concentration. The EO effects of the dye-doped PSCT films are measured and a photovoltage is found to be created during pumping with an Ar+ laser. The polymer networks in the cell markedly slow down the diffusion and migration velocity of photocharges in this experiment.
