摘要：Effect of halide ions to the formation of gold nanoparticles via the gold-deposition development was investigated. Development rate for a silver-chloride emulsion was small, and that for a silver-bromide one was fairly large, while that for a silver iodobromide emulsion was much larger than these rates. The rate with a developer including only chloride ions was small, but this increased by the addition of bromide ions. Addition of small amount of iodide ions caused large increase in the rates for some emulsions. Iodide ions are essential to increase in the development rates, but the degree of increase differed among the emulsions used in this study. The rates were also different for each of the emulsion-manufactures, suggesting the influences of gelatin or some additives peculiar to them. It was speculated that other factors in addition to iodide ions affected the rates of the gold-deposition development.
