分别采用香豆素6（C6）掺杂的聚间己氧基苯基硅烷（PHPPS）、罗丹明6 G（R6 G）掺杂的聚甲基苯基硅烷（PMPS）和酞菁锌（ZnPc）/三-8-羟基喹啉铝（Alq 3）双层膜制备了对蓝光、绿色和红光敏感的有机光电导体。这些膜的光谱响应的选择性足够好，以将入射光分成三个颜色分量，表明无棱镜摄像机的颜色分离的可能性。ZnPc/Alq 3双层膜的量子效率比C6/PHPPS和R6 G/PMPS共混膜的量子效率高一个数量级以上，这是由于ZnPc/Alq 3界面处产生的电子-空穴对解离所致.
Organic photoconductors sensitive to blue, green, and red light were fabricated using coumarin 6 (C6)-doped poly(m-hexoxyphenyl)phenylsilane (PHPPS), rhodamine 6G (R6G)-doped polymethylphenylsilane (PMPS), and zinc phthalocyanine (ZnPc)/tris-8-hydroxyquinoline aluminum (Alq3) double layer, respectively. Selectivities of the spectral responses of these films were good enough to divide the incident light into three color components, indicating the possibility of color separation without prism for video cameras. The quantum efficiency of a ZnPc/Alq3 double-layer film is over an order of magnitude better than those of C6/PHPPS and R6G/PMPS blend films due to the dissociation of electron–hole pair generated at the interface between ZnPc and Alq3.
