In order to collectively study the factors influencing the developability of centers, the in situ measurement and analysis of the rate of development was made for various latent image centers and fog centers on AgBr grains with a variation of the kind of chemical sensitizations. The developability of these centers was analyzed from the viewpoints that the electron transfer from a developer to the electron-accepting level of a center should initiate the development, and that the height of the electron-accepting level of a center should be related to its size, chemical composition, band structure, the parity of the number of valence electrons in it, and the site for its formation. It was confirmed that the smallest developable center in AgBr emulsions was a fog center composed of two Au atoms while the smallest latent image centers in the emulsions with and without gold sensitization were Ag2Au and Ag4 , respectively. The developabilities of these smallest centers were much smaller than those of larger ones. The developability of a center with a forbidden band as exemplified by Ag2S (i.e., a fog center in a sulfur sensitized emulsion) was so small that several hundreds of nanoclusters per grain were needed to initiate the development of the grain.

More about this publication?
  • The Journal of Imaging Science and Technology (JIST) is dedicated to the advancement of imaging science knowledge, the practical applications of such knowledge, and how imaging science relates to other fields of study. The pages of this journal are open to reports of new theoretical or experimental results, and to comprehensive reviews. Only original manuscripts that have not been previously published, nor currently submitted for publication elsewhere, should be submitted.

    IS&T's JIST-first publication option allows authors wishing to present their work at conferences, but have a journal citation for their paper, to submit a paper to JIST that follows the same rigorous peer-review vetting and publication process as traditional JIST articles, but with the benefit of a condensed time-to-publication time frame and guaranteed conference presentation slot.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
