| Popis: | We demonstrated a blue-sensitive organic photoconductive device fabricated by an electrospray deposition method. Poly[9,9-dioctylfluorenyl-2,7-diyl]-co-1,4-benzo-(2,1,3)-thiadiazole (F8BT) was chosen as a blue-sensitive polymer, and a maximum external quantum efficiency of 0.22% was achieved at the irradiated optical intensity of 3.9 mW/cm 2 . The absorption spectrum of F8BT neat film showed that the selectivity of spectral responses at the blue wavelength region was good enough to divide the incident light into blue color components. These results indicate the possibility of a color separation without a prism for high resolution cameras by combination of green and red sensitive organic photoconductive devices. |
