| Research Abstract |
Gold-deposition development method was investigated from both points of the reaction mechanism and its application. Photolitic silver clusters formed on the exposed area of silver-salt photographic materials act as a catalyst to prepare gold nanoparticles. Drastic increase in reaction rate was obtained by the addition of ascorbic acid and the reaction mechanism was analyzed from the temperature dependence, etc. The fine photographic images prepared by this method were applied to the analysis of radiation tracks and preparation of gold-layer photographs, which produced fruitful results of the analysis of energy loss of the tracks or long-term image preservation.
