We report on a fast and efficient polymeric photorefractive (PR) device by using single-walled carbon nanotubes (SWCNTs) on indium-doped tin oxide (ITO) electrodes. In presence of SWCNTs, the magnitudes of photocurrent, space charge field, and refractive index modulation increased 56.9%, 20.3%, and 22.1%, respectively, due to enhanced charge separation and facilitative charge transport. The PR grating buildup speed of PR device with SWCNTs layers was three-and-a-half times faster than that without SWCNTs layers. The SWCNTs with layer structure provided an efficient electron-transfer matrix.

Keywords:single-wall carbon nanotubes (SWCNTs);grating buildup speed;space charge field;photocurrent
