Abstract:

We have found that nanoparticles of silver iodide have high sensitivity for blue light and are fixed during thermal development in photothermographic materials. Silver iodide particles exhibit high sensitivity and weak LIRF in photothermographic materials, as they do in conventional materials with higher silver ion concentration than usual, and have their sensitivity further improved by reducing agents adsorptive to the particles. The sensitivity of photothermographic materials with nanoparticles of silver iodide for blue laser light could be comparable to that of the materials with silver iodobromide for red laser light. Silver iodide particles are slowly fixed during thermal development in photothermographic materials with existence of either silver carboxylate or phthalazine, and rapidly fixed with coexistence of these two compounds. Fog density of developed layers of photothermographic materials with nanoparticles of silver iodide does not increase under room light illumination.

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.
