An approximately 700 nm thick film of 1D-Na2Ti6O13 nanorods, synthesized by heating a mixture of Natitanate nanotubes and NaCl at 810°C, was fabricated using LBL-SA technique. To improve the photoactivity
of the coated film, CuxS, In2S3 and CuInS2 were synthesized and incorporated into the film by the polyol process. The thicknesses of CuxS, In2S3 and CuInS2 films incorporated into the film were 2 μm, 2 μm, and 40 μm, respectively. A deterioration of photocurrent was observed with the film incorporated with In2S3particles. However, the films with CuxS or CuInS2 showed improved photocurrent, and the onset voltage was also reduced to 0.4 V. The performance of the films incorporated with 40 μm thick CuInS2 were affected by the light direction; a higher photocurrent was measured with the light illuminated through opposite side of the film.
