Non-polymer organic thin films, copper-phthalocyanine (CuPc) and 4-dialkylamino-4′-nitrostilbene (DANS), were fabricated by KrF laser ablation. Crystalline thin films with almost the same composition as the target material were deposited when reducing the laser ablation fluence close to the ablation threshold of ∼ 20 mJ/cm 2 . Higher laser fluences deplete some weakly bound atoms in the thin film, such as nitrogen in CuPc. Semiconductor characteristics of CuPc thin film were examined in a Schottky diode. DANS-doped amorphous fluoropolymer was also fabricated by combining two ablation deposition processes. A crystalline feature of DANS disappears at low DANS concentrations in a fluoropolymer matrix.
