Thin Au-In films were prepared by thermal co-evaporation and studied by the means of energy dispersive X-ray analysis, X-ray diffraction, scanning electron microscopy and spectroscopic ellipsometry. The alloying tendency in the as-deposited thin films was analysed and the influence of the AuIn2 and Au7In3 compounds on the optical properties and the possibility for excitation of a plasmon resonance in the bimetallic condensates was analysed.
