在这封信中，我们报告了一种新的放射性光致发光（RPL）材料的发现。在真空烧结的非掺杂K2CO3陶瓷中，RPL表现为峰值位于440 nm的PL发射带的演化。RPL信号被证实对X射线敏感，并且在室温下稳定。尽管样品未优化，但观察到RPL响应低至1 mGy。我们坚信，这种材料应该是一个有前途的候选人作为RPL剂量计材料。
In this letter, we report a discovery of a new radio-photoluminescence (RPL) material. The RPL appeared in vacuum-sintered non-doped K2CO3ceramics as an evolution of PL emission band peaking at 440 nm. The RPL signal was confirmed to be sensitive to X-rays and stable at room temperature. The RPL response was observed as low as 1 mGy although the sample was not optimized. We strongly believe that this material should be a promising candidate as RPL dosimeter materials.
