摘要
本文观察到了 Ca3(PO4)2：Ce3+的超长持续紫外A型发光。晶体结构分析表明，制备的样品是纯净的 β-Ca3(PO4)2 相，具有斜方体结构和 R3c 空间群。样品的光致发光光谱都在 340-400 nm UVA1 区有一个宽带，该宽带被归因于 Ce3+ 离子的 5d1-4f1 电子转变。更重要的是，在 3 分钟的 X 射线照射下，Ca3(PO4)2：更重要的是，在 3 分钟的 X 射线辐照下，Ca3(PO4)2: Ce3+ 在 UVA1 区域显示出超长的持续发光，可持续 16 小时以上。此外，仅 10 秒钟的 X 射线照射就能诱导 Ca3(PO4)2: 0.08Ce3+ 发出极好的长持续 UVA 发光，可持续 5 小时以上，余辉发射强度约为背景强度的 3.03 倍。阱分析证实，不同的 X 射线辐照时间并不会产生新的阱，即使在极低的 X 射线剂量下（10 秒 X 射线辐照），阱深度为 0.75 eV 的阱仍然存在。此外，在 10 秒的 X 射线辐照下，Ca3(PO4)2: 0.08Ce3+ 的热致发光（TL）强度在 120 分钟后仍能达到初始 TL 强度的 0.32 倍，从而实现了超长持续发光。因此，高能 X 射线辐照诱导的大量截留电子是 Ca3(PO4)2: 0.08Ce3+ 超长持续 UVA 发光的主要原因：Ce3+。
X-ray-activated super long persistent ultraviolet A luminescence from Ca3(PO4)2: Ce3+
In this paper, X-ray-activated super long persistent ultraviolet A luminescence from Ca3(PO4)2: Ce3+ has been observed. The crystal structure analysis has shown that the as-prepared samples are pure β-Ca3(PO4)2 phases with rhombohedral structure and R3c space group. The photoluminescent spectra of the samples all consist of a broad band in 340–400 nm UVA1 region, which is assigned to the 5d1–4f1 electronic transition of Ce3+ ions. More important, under the 3 min X-ray irradiation, Ca3(PO4)2: Ce3+ show super long persistent luminescence in the UVA1 region, which can persist for more than 16 h. And its afterglow intensity after 16 h decay is still 4.10 times stronger of the back ground intensity. Furthermore, only 10 s X-ray irradiation can induce excellent long persistent UVA luminescence of Ca3(PO4)2: 0.08Ce3+, which can persist for more than 5 h and afterglow emission intensity is about 3.03 times of the background intensity. The trap analysis has confirmed that the different X-ray irradiation time do not create new traps and there is the same trap with 0.75 eV trap depth existing even under the extremely low X-ray dose (10 s X-ray irradiation). Furthermore, under 10 s X-ray irradiation, the thermoluminescence (TL) intensity of Ca3(PO4)2: 0.08Ce3+ still reaches 0.32 times of the initial TL intensity even after 120 min, which thus leads to the super long persistent luminescence. Thus, the large amounts of trapped electrons induced by the high energy X-ray irradiation are the principal cause for super long persistent UVA luminescence of Ca3(PO4)2: Ce3+.
期刊介绍：
The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials.
Papers on fundamental ceramic and glass science are welcome including those in the following areas:
Enabling materials for grand challenges[...]
Materials design, selection, synthesis and processing methods[...]
Characterization of compositions, structures, defects, and properties along with new methods [...]
Mechanisms, Theory, Modeling, and Simulation[...]
JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
