Photographic film emulsions

In industry, iodine is used for dyes, antiseptics, germicides. X-ray contrast medium, food and feed additives, pharmaceuticals, medical soaps, and photographic film emulsions and as a laboratory catalyst to either speed up or slow down chemical reactions. [Pg.256]

Most modem silver mined has been used to make photographic film emulsions, in plating, and in alloys for tableware, jewelry, and electrical equipment. Sterling silver is an expression of purity, being at least 92.5% silver. This is expressed either with the word sterling, 0.925 (the is often omitted), or the Lion Passant hallmark. Fine silver is 99.9% pure, but is too soft for most applications. This is the standard purity for silver bullion, as a commodity. [Pg.28]

Lesser amounts of sodium thiocyanate are used in color toning photographic paper, as a stabilizer in rapid film development, and as a sensitizing agent in color negative-film emulsions. It is also used as a brightener in copper electroplating. [Pg.152]

Other detection modes in bright CL or BL reactions are multichannel detectors, which provide simultaneous detection of the dispersed radiation and produce a permanent image of a wide area. Photographic films or plates are emulsions that contain silver halide crystals in which incident photons produce stable clusters of silver atoms within the crystals. Internal amplification is provided in the development process by an electron donor that reduces the remaining silver ions to silver atoms within the exposed crystals. A complexing agent is used to remove the... [Pg.56]

It has been found that only a few photons, maybe as little as six, are needed to form the latent image. Photographic film is a very sensitive light detector. The final step in the photographic process, fixing, removes the unreacted silver bromide crystals from the emulsion, thus stabilizing the image (Fig. 2.4). [Pg.59]

As another example of utilizing platy forms of twinned crystals, we should mention a recent remarkable increase in the photosensitivity of photographic film. Photographic emulsion film consists of minute AgBr crystallites, with octahedral or cubo-octahedral Habitus. The photosensitivity is determined by the area... [Pg.132]
