Orientation of vanadyl-phthalocyanine film prepared by molecular beam epitaxy and treated in organic gas

In this paper, the VOPc film was prepared on KBr substrate by OMBD. After that, it was treated in organic gas. The thickness of VOPc film was 96 nm. The morphologies of VOPc film before and after the gas treatment were characterized with optical absorption spectra and SEM image. The third- harmonic generation of VOPc film before and after the gas treatment were also measured by Maker fringe method using a Nd:YAG laser.
