Phthalocyanines are promising candidates for several optoelectric devices, small molecular organic solar cells or chemiresistive gas sensors. Phthalocyanine thin films are most commonly fabricated by vacuum evaporation technique. Pulsed Laser Deposition (PLD) was recently also shown as successful PVD technique to fabricate these films. We chose Zinc Phthalocyanine (ZnPc) as representative example to compare optical and electrical properties. ZnPc thin films were fabricated by organic molecular evaporation (OME) and PLD in vacuum on fused silica substrates at room temperature. PLD used a KrF laser (λ=248 nm, τ=5 ns), where laser fluence was varied in the region from 10 mJ.cm-2 to 100 mJ.cm-2 and frequency in the interval from 50 Hz to 200 Hz. Optical properties were characterized by optical spectroscopy, spectrophotometric measurement and spectral ellipsometry. The electrical properties were analyzed by van der Pauw method. Electronic structure was analyzed by XPS.
