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... 

The silver halide crystals can be formed as microscopic grains suspended in a protective colloid, usually gelatin. This dispersion, the photographic emulsion, can be coated on a suitable support to obtain photographic films, plates, and papers. 

With silver halides sodium thiosulphate forms a soluble sodium silver thiosulphate, and is employed as a fixing material for photographic plates and paper to remove the portion of silver salt unaffected by light ... 

Soon after the discovery of the silver halide photographic plate, researchers found that light was not the only factor capable of forming a latent (developable) image on a photographic film. The first of these... 

The increased interest in energy sensitive polymers probably evolves from the shortcomings of the conventional image recording media-silver halide emulsion. It is both difficult and expensive to apply emulsion films as protective layers or use as printing plates or etch resists. Synthetic polymers are one to two orders of magnitude less radiation sensitive than halide emulsion, but their unique properties of chemical and physical resistance easily overcome this disadvantage, ( ., Table IV). 

The density of the photocolor image increases by adding a proper coupler to the azide compound. It is possible to fix the colored image using the photo-polsrmers containing these azide compounds and novolak. In future, it may be possible to use this photocolor film for plate making instead of silver halide emulsion film.
