Photoprocess in AgBr microcrystals in the presence of Pt(II) and Pd(II) complex ions

Results of a systematic study of the chemical sensitization of cubic-faceted AgBr emulsion microcrystals with complex compounds K 2 [XY 4 ] and Na 6 [XZ 4 ] [X = Pd, Pt; Y = Br − , Cl − , SCN − ; Z =(SO 3 ) 2− ] were considered. The role of secondary dissociation of complex ions during the chemical...

Description
Summary:Results of a systematic study of the chemical sensitization of cubic-faceted AgBr emulsion microcrystals with complex compounds K 2 [XY 4 ] and Na 6 [XZ 4 ] [X = Pd, Pt; Y = Br − , Cl − , SCN − ; Z =(SO 3 ) 2− ] were considered. The role of secondary dissociation of complex ions during the chemical sensitizing was established. Conditions were determined in which the compounds specified can be used as chemical sensitizers of AgBr. The effect of these complexes on the basic photographic characteristics was demonstrated.
