摘　　要：Nanometer multilayer composite films of lead phthalocyanine(PbPc) and vanadyl phthalocyanine(VOPc) were prepared by vacuum vapor deposition. It is found that a new absorption peak around 940 nm appeared as discovered by UV-visible absorption analysis. Compared to the Q bands absorption of single component films of VOPc and PbPc, the new peak is red-shifted. It is also found that the new peak shows a small red-shift when the thickness of the PbPc layer increases. It is concluded that the new peak is a result of composition, and the red-shift is caused by both interface effect and quantum confinement effect of the nanometer multilayered structure.Nanometer multilayer composite films of lead phthalocyanine(PbPc) and vanadyl phthalocyanine(VOPc) were prepared by vacuum vapor deposition.
