| Abstract: | This article reports the photoconductive spectra of poly-N-vinylcarbazole: 2, 4, 7-trinitro-9-fluorenone (1:0.5 molar ratio) charge transfer complex (CTC) obtained with sandwich and surface cells.The effects of wavelength, field strength and polarity of the illuminated electrode on Lux-Ampere index y are discussed. Two kinds of photocarrier generation are suggested. When λ>500nm, the photocarriers were generated by light absorption of the charge transfer complex; when λ<500nm, the phptoearriers were produced by poly-N-vinylcarbazole and 2, 4, 7-trinitro-9-fluorenone free molecules present in the film. |
