Abstract: 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.

Key words: Metallophthalocyanine, Layered composite film, UV-Vis absorption
