Abstract : The luminofor, activated by other metals for photographic registration in the infrared region, is distinguished by the facts that the zinc sulfide is free of deleterious metal impurities exceeding 1,000,000 percent by weight of the zinc sulfide, and is activated by copper, lead or cobalt, none of which may exceed 1,000-10 to the 7th power percent of the zinc sulfide in either the activator or the flux used. This patent covers luminofor, a substance sensitive to infrared radiation in the spectral region up to 2500 microns in which infrared radiation is evidenced by extinction of phosphorescence.
