Abstract
AbstractInternally sulphur-plus-gold-sensitized core/shell emulsions (0.65-µm AgBr octahedra) are used as a Model system in which to study internal latent-image formation. Optimum internal development conditions utilize Kodak rapid x-ray developer to which is added 0.1 g KI/l, the development time being 25 min. No significant nonuniformity in depth of KI is observed. These core/shell emulsions are highly sensitive, requiring 4 ± 1 absorbed photons/grain to make half the grains developable after correcting for fog. Combining experimental data with model predictions indicates that the minimum developable size of the internal latent image is three atoms. This result is confirmed by lightlatensification experiments. Contrary to what might be expected, the minimum developable size for our experimental conditions is the same whether the latent image is located at internal or surface sites. The experimental results are in good agreement with the predictions of the nucleation-and-growth model of latent-image form...
