Abstract
818,108. Luminescent materials. BRANDHURST CO. Ltd. Feb. 27, 1958 [Feb. 28, 1957], No. 6711/57. Drawings to Specification. Class 39(1). A luminescent material, such as copperactivated zinc sulphide, contains an artificial radioactive isotope selected from the transuranic elements and emitting mainly alpha radiation with little or no beta or gamma radiation. The radioactive isotopes americium 241, plutonium 239 and curium 242 are preferred but neptunium 237, plutonium 236, 238, 240 and curium 244 may also be used. The hazards normally encountered in the manufacture and use of self-luminous compositions due to the emission of penetrating gamma radiation and toxic gas are greatly reduced and the quality of an americium luminous composition can be assessed immediately after its manufacture. In the preparation of such a composition a salt of americium 241 is dissolved in water and added to a chemically inert substance, such as silica aerogel. The isotope is then precipitated on the surface of the inert substance and after the water has been removed by evaporation it is dispersed in methanol to which is added copperactivated zinc sulphide. Finally the methanol is removed by evaporation with or without filtering to provide a self-luminous composition emitting light in the yellow-green region of the visible spectrum. This composition may be mixed with methyl methacrylate resin and solvent to provide a paint suitable for application to instrument dials and clock or watch dials.
