Photorefractive quantities of diffraction efficiency, optical gain, and grating buildup speed were investigated for newly prepared polycarbazoylethylacrylate (PCzEA) composites with photoconductive plasticizer of carbazoylethylpropionate (CzEPA) in comparison with those with a commonly used plasticizer of benzyl n-butyl phthalate. CzEPA is a model compound of PCzEA and works as a good plasticizer with photoconductive performance. Diffraction efficiency of 7.5% and grating buildup speed of 4.3 s−1 (response time of 235 ms) were measured at lower electric field of 45 V µm−1 for the composite with CzEPA plasticizer. Furthermore stable optical gain of 51 cm−1 was measured because of lower absorption coefficient of 10 cm−1 at 632.8 nm.
