Description

The proposed iisoopoTcniic relates to a device for fluorescent screen, designed to make it almost or almost completely transformed by electric or electro-energy energy, such as cathode, remittance and radon-active beams, into visible light. As before, a variety of substances can be used as a fluorescent substance, such as silicon, silicate, and ka (Miyu tungstate for Reitgei screens, calcium tungstate for Reitgen amplifying films. Screens of activated sulphite, activated with copper, are used mainly for teporous films. In order to convert electrical and electromagnetic energy into visible light, copper sulphite screens are activated by copper, are inconvenient in view of the phosphorescent ability, oot appears in the afterglow under the influence of preceding excitement / cdepi.

also zinc sulphites, but possessing or possessing a very healthy steppe step after all the time: a thoroughly cleaned preparation of sulphite, which fluoresces with blue-violet light, as well as cn-sulphite fluorescent with different colors. The condition is. so that the manufacture of irradiating metal, especially copper, was not made at manufacture, since preparations of cico-cadmium sulfite produce an afterglow when activated by adding copper only in the amount of Viooooo. Recently, a further cn-cadmium fluorescent substance from sulfite has been described, silver, containing cadmium sulfite. Therefore, a silver-activated zinc-cadmium sulfite substance should behave almost as much as not an active substance of the same composition. This takes place mainly in the case of a small content of cadmium sulfite (up to).

For a higher cadmium sulfite content, a systematic difference was struck during systematic research. It turned out that with a deeper fluorescent coloration it is an interest in the luminophorism. silver-activated significantly exceeds that of activating, and that with a higher content of cadmium sulfite, without silver activation, it is hardly possible to obtain a technically suitable phosphor. The most important and valuable property of a fluorescent substance, obtained for the first time due to the proposed invention (not to mention the luminous efficacy of other fluorescent substances), is the absence of an afterglow in the preparations, fluorescence depending on the admixture of cadmium sulfite from green-yellow to red Sveta. The invention of this new phosphor makes it possible to significantly improve the quality of fluorescent screens (both in otishetsii, luminous efficacy, and in relation to svbrydy from. Nose light) in Braujovskih trroff, in X-ray and translucent screens, and in X-ray

amplifiers. Wonderful yet. Due to the ability of zinc-cadmium preiaratov to give different colors of luminescence depending on the nocotitic content of cadmium sulfite, it is possible to mix different substances of this drug with one another or with other luminous substances, so that you can get any color and even white light. The methods for preparing a new luminophore are not significantly different from those found in the literature many times for the preparation of phosphors from zinc sulphite or zinc-cadmium sulfate.

Subject and d ore and and.

A fluorescent screen, and is intended for a non-hyperfacial or near-inertia leveling of an electrical electromagnetic field (cathode, radioactive and X-rays) into visible light, characterized by the use of cadmium sulphite as fluorescent and its active silver cadmium sulfite, active silver with a content of cadmium sulfite more
