    摘要： A photographic silver halide emulsion is disclosed comprised of radiation sensitive composite silver halide grains including host grain portions accounting for at least 50 percent of total silver and surface portions epitaxially deposited on the host grain portions. The epitaxially deposited surface portions on the host grain portions exhibit a face centered cubic crystal lattice structure containing a hexacoordination complex of a metal from periods 4, 5 and 6 of groups 3 to 14 inclusive of the periodic table of elements in which one or more organic ligands each containing at least one carbon-to-carbon bond, at least one carbon-to-hydrogen bond or at least one carbon-to-nitrogen-to-hydrogen bond sequence occupy up to half the metal coordination sites in the coordination complex and at least half of the metal coordination sites in the coordination complex are provided by halogen or pseudohalogen ligands.

    摘要： A radiation-sensitive emulsion comprised of silver halide grains (a) containing greater than 50 mole percent chloride, based on silver, (b) having greater than 50 percent of their surface area provided by {100} crystal faces, and (c) having a central portion accounting for up to 99 percent of total silver and containing a first dopant of Formula (I) and a second dopant of Formula (II): [RuL6]n  (I) wherein n is zero, −1, −2, −3 or −4, and L6 represents bridging ligands which can be independently selected, provided that at least four of the ligands are anionic ligands, and at least one of the ligands is a cyano ligand or a ligand more electronegative than a cyano ligand; [TE4(NZ)E′]r  (II) wherein T is Os or Ru; E4 represents bridging ligands which can be independently selected; E′ is E or NZ; r is zero, −1, −2 or −3; and Z is oxygen or sulfur; wherein the dopant of Formula (II) is selected from hexacoordination complexes which form deep electron traps in silver chloride grains by providing an incorporated molecular entity having a lowest unoccupied molecular orbital which is at least 0.5 eV below the conduction band of the silver chloride grains, where (i) less than 60% of the deep electron traps empty within 2000 seconds at 300 K after being filled and (ii) between 15-60% of the deep electron traps empty within 12,000 seconds at 300 K after being filled. Improved latent image keeping performance can be obtained for optical and digital exposed elements which comprise silver halide grains in an emulsion layer doped with a dopant of Formula (I) and a dopant of Formula (II) as described above, while substantially maintaining other desired photographic parameters.

    摘要： A process is disclosed of preparing a radiation sensitive silver halide emulsion comprising reacting silver and halide ions in a dispersing medium in the presence of a metal hexacoordination or tetracoordination complex having at least one organic ligand containing a least one carbon-to-carbon bond, at least one carbon-to-hydrogen bond, or at least one carbon-to-nitrogen-to-hydrogen bond sequence and at least half of the metal coordination sites occupied by halide or pseudohalide ligands. The metal forming the complex is chosen from periods 4, 5 and 6 and groups 3 to 13 inclusive of the periodic table of elements. The incorporation of the transition metal ion dopant and at least one organic ligand into the cubic crystal lattice of the silver halide grains can be used to improve photographic performance.
