Abstract

Deposition rate during laser evaporation is about 3-5 times higher than during thermal evaporation. Evaporated malonitrile-based merocyanine (Mc) and phtalocyanine (Pc) dyes from smooth films with high optical absorption and reflection in visible and near-IR regions. PcVO film, deposited at 20 degrees C consists of high temperature crystal phase. Co-deposition of polymer and dye showed that the films consists of the polymer matrix filled by dye nanoparticles. Polystyrene and polychlorotrifluoroethylene were used. It was known before, that low temperature plasma treatment of some dye vapors led to their polymerization and stability enhancement, but specific optical properties were reduced strongly. We tried to adjust dye chemical structure and plasma parameters. Films enhance their adhesion and stability significantly, retaining high optical absorption. Their spectra have some peculiarities, but main peaks are the same as for the parent dye.
