Purple Au-Al alloy films were deposited on glass substrates using a radio frequency ion plating method. Au-Al alloys were used as source materials. The effects on the film of the source alloy composition and the evaporation time were studied. The color tones of the deposited films were measured using spectral reflectance and their crystal structures were studied by X-ray diffraction. As a result, a composition of Au 80%-Al 20% was chosed as the most suitable source alloy. The color tone of a film deposited from a single evaporation source changed from white to purple as the evaporation time increased. The intensity of the X-ray diffraction pattern of the AuAl<sub>2</sub> sharpened as the color tone of the film became more purpler. The purple color of the film became brighter after 1hour of heat annealing at 550°C in an atmosphere of Ar (8×10<sup>3</sup>Pa).
