In order to make clear the darkness of gold film, a recently developed method has been performed for gold film and Pb ultrafine particles. The reaction between gold film and Pb particles occurred above 100℃. The alloy formation has been formed near Pb particles in the gold film. The diffusion of Pb atoms into gold particles clearly observed. The darkness of gold film putting Pb particles is also verified by the irradiation of the sun light. The ultraviolet radiation is assisted the darkness of gold film. The darkness of gold film has been discussed as the problem of environment pollution which can be seen in gold temple in Kyoto Japan (Kinkakuji Temple).
