A novel radio-photoluminescence material featuring fluorochromic responses toward UV or X-ray irradiation has been obtained. Such a unique monomer- to excimer-based luminescence transition allows for dosimetry of ionizing radiation in a ratiometric manner. Rather than quenching the luminescence, the radiation-induced radical species of Th-105 boost the excimer emission, rendering it as a rare material possessing radical-excimers.
一种新型的对紫外线或X射线照射具有荧光变色响应的放射光致发光材料已被获得。这种基于单体到准分子的独特发光转变允许以比率方式对电离辐射进行剂量测定。Th-105的辐射诱导自由基物种不是淬灭发光，而是增强准分子发射，使其成为一种拥有自由基准分子的稀有材料。
