    • Novel compounds obtainable by reacting together an imido-reagent such as diphenylphosphonimido-triphenylphosphorane), or a phosphine oxide such as p-tolyldiphenylphosphine oxide, with a chelate of a transition or lanthanide or actinide metal, such as tris(dibenzoylmethide)europium III, have the property of fluorescing in UV radiation. The invention includes solid polymer bodies containing such compounds, or chelates of transition or lanthanide or actinide metals generally, the bodies having the property of emitting light or infra-red radiation when subjected to a flux of ultra-violet or ionising radiation by virtue of internally generated, e.g. by tritium ionising radiation. The body is preferably of polystyrene formed by polymerising the monomer in the presence of the compound or metal chelate.
    • 通过使亚氨基试剂如二苯基亚膦酰基 - 三苯基正膦或其氧化膦如对甲苯基二苯基氧化膦与过渡或镧系元素或锕系金属螯合物如三(二苯甲酰甲基)铕III的螯合物反应得到的新型化合物具有三 在紫外线辐射下发荧光的特性。 本发明包括含有这些化合物的固体聚合物体,或过渡或镧系元素或锕系金属的螯合物,通常通过内部经受紫外或电离辐射的通量而具有发射光或红外辐射性质的物质 生成,例如 通过氚电离辐射。 身体优选是通过在化合物或金属螯合物的存在下聚合单体而形成的聚苯乙烯。
