热处理氟氯锆酸盐（FCZ）玻璃使玻璃基质中的纳米晶体成核，形成具有适合用作医学成像板的光学特性的纳米复合玻璃陶瓷。了解纳米晶体成核的进行方式对于控制光学行为至关重要。在原位透射电子显微镜加热实验中研究了 FCZ 微晶玻璃中纳米晶体的成核和生长。实验显示，除了预期的 BaCl2 纳米晶体之外，还出现了先前未报道的 BaF2 纳米晶体的成核和生长。 BaF2 纳米晶体的化学分析表明与光学活性掺杂剂有关，以前认为该掺杂剂仅与 BaCl2 纳米晶体相互作用。掺杂剂与 BaF2 晶体的结合表明它在 FCZ 微晶玻璃的光致发光 (PL) 性能中发挥着重要作用。
Heat treating fluorochlorozirconate (FCZ) glasses nucleates nanocrystals in the glass matrix, resulting in a nanocomposite glass‐ceramic that has optical properties suitable for use as a medical imaging plate. Understanding the way in which the nanocrystal nucleation proceeds is critical to controlling the optical behavior. The nucleation and growth of nanocrystals in FCZ glass‐ceramics was investigated within situtransmission electron microscopy heating experiments. The experiments showed the nucleation and growth of previously unreported BaF2nanocrystals in addition to the expected BaCl2nanocrystals. Chemical analysis of the BaF2nanocrystals shows an association with the optically active dopant previously thought only to interact with BaCl2nanocrystals. The association of the dopant with BaF2crystals suggests that it plays a role in the photoluminescent (PL) properties of FCZ glass‐ceramics.
