Mixed alkaline earth sulfate phosphor fluorescent screens and radiographic elements |
| abstract |
Novel phosphors comprising lanthanide-activated plural mixed alkaline earth sulfates such as europium-activated strontium barium sulfate, are prepared by coprecipitation of the lanthanide ion and said plural alkaline earth ions in dilute solution. The phosphors show high efficiency of fluorescence when excited by xrays and are particularly useful in intensifying screens in combination with radiographic image recording elements. |
