A photoreceptor consisting of 6-nitro-spiropyran and TCNQ films was constructed. TCNQ Langmuir-Blodgett (LB) films were deposited onto the pretreated quartz substrate and its photoelectric effect was verified. The photocurrent generated by TCNQ was proportional to the light intensity. The other side of the quartz substrate was deposited by spiropyran with long alkyl chain using the spin-coating technique. The absorbance change of the spiropyran films irradiated by UV light was proportional to the light intensity on irradiation with green light. The maximum absorbance change of spiropyran film was observed at 595 nm and the saturation of the absorbance change occurred after 30 min under continuous irradiation of UV light. In the constructed photoreceptor, the increment of the intensity ratio of transmitted light in comparison with that of input light was obtained when two input lights with the different light intensity were irradiated on the films. Depending on the intensity of transmitted light, the photocurrent was generated by TCNQ LB film. By this process, the ratio of output photocurrent generated by the transmitted light larger than the ratio of input light intensity could be obtained, which can be applied to the construction of the image sensor to extract the desired image. The extraction efficiency of the proposed photoreceptor was about 10% with 15 min of extraction time.
