Silver compounds light sensitivity

Silver Halide Light-sensitive compound used in photographic film and paper. 

All the silver halides are sensitive to light, decomposing eventually to silver. In sunlight, silver chloride turns first violet and finally black. The use of these compounds in photography depends on this (see below). (All silver salts are, in fact, photosensitive—the neck of a silver nitrate bottle is black owing to a deposit of silver.)... 

AgPh is a colourless solid [144] that is rather insoluble in non-donor solvents and appears to be polymeric (AgPh) (n > 10) in addition mixed compounds (AgPh) .AgN03 (n = 2,5) can also be obtained that involve silver clusters. Mesitylsilver is a thermally stable (but light-sensitive) white crystalline solid in the solid state it is tetrameric (in contrast to the pentameric copper and gold analogues) ... 

Photography based on silver halides as the light-sensitive material depends on physical and chemical properties that, although occurring individually in other compounds, form a combination in the silver salts that makes them unique in their... 

Silver halide grains are used as the light-sensitive component in many solution processes involving physical development. The latent images or partially developed latent images comprise the nuclei upon which the physical development reactions are catalyzed. There are many other nuclei-forming compounds, however, which find use in systems where the speed of silver halide is not required, its expense is unsuitable, or a more efficient catalyst for the physical development reaction is desired. 

In a photothermographic system disclosed by Itek Corporation, the light-sensitive element is a silver halide and the image-forming material is the silver salt of EDTA or a related compound.200... 

Silver(I) Fluoride. Silver(I) fluoride, like the mercury fluorides, has been used as a fluorinating agent for many years. It can be used in most of the reactions for which other inorganic fluorides are used. Its use has declined in recent years, primarily because it is deliquescent, light-sensitive, and easily reduced. Only one-half of its fluorine is available for fluorination because it forms the compound AgCl-AgF, which has very little fluorinating power. 

Silver forms monovalent ion in solution, which is colourless. Silver(II) compounds are unstable, but play an important role in silver-catalysed oxidation-reduction processes. Silver nitrate is readily soluble in water, silver acetate, nitrite and sulphate are less soluble, while all the other silver compounds are practically insoluble. Silver complexes are however soluble. Silver halides are sensitive to light these characteristics are widely utilized in photography. 

Photolysis of metal compounds is a method of historical dimension as it has been used since the middle of the nineteenth century, when the light-sensitivity of silver salts was used for photographic purposes. Novel research, especially linked with the names Henglein and Belloni, led to a large extended field in the science of nanoparticles. UV-visible irradiation of Au, Ag, and Pt salts in surfactant or polymer solutions end up with nanoparticle formation. " Compared with hydrogen reduction, photolytic reactions usually give smaller particles with narrower size distribution. ...
