✦ Synopsis

We have experimentally and theoretically studied the thermal dependence of holographic gratings based on near infrared sensitive polymer dispersed liquid crystal films. Experimental results indicate that the diffraction efficiency of our grating changes non-monotonically with the increase of the sampleÕs temperature. The main contributing mechanism is the heat-induced change of the liquid crystal refractive index.

We report on the structures and electro-optical properties of epoxy/acrylic polymer-dispersed liquid-crystal (PDLC) films. A thermal stimulated current (TSC) analysis was used to investigate the physical structures of PDLC. In the TSC spectrum of PDLC, three relaxation peaks were observed: the glass
