摘要：
The photorefractive properties of polymer composites based on poly(N-vinylcarbazole), doped with the sensitizer C-60, the plasticizer butyl benzyl phthalate, and two series of chromophores are presented. The influence of the structure and the oxidation potential of the chromophore on the photorefractive properties is discussed. These materials show promise for video-rate optical processing applications,since they exhibit fast response times (beam-coupling growth times, tau(g), as small as 60 ms at 50 V/mu m applied field and 200 mW/cm(2) intensity and tau(g) as small as 5 ms at 100 V/mu m and 1 W/cm(2)).
