Abstract
This invention relates to new phosphor materials exhibiting luminescence and methods for their production. More particularly, the invention relates to new europium-doped zinc sulfide-manganese (ZnS:Mn,Eu) phosphors and use thereof for radiation detection.
Claims8
A luminescent phosphor material comprising ZnS:Mn that is doped with Eu2+ ions.
A process for the preparation of a particle dispersion of zinc sulfide doped with manganese and europium ions (ZnS:Mn, Eu2+) comprising the step of mixing powders of zinc sulfide, MnCl2 and EuCl2 and sintering in the presence of charcoal.
