A simple and effective template-mediated protocol has been developed for the large-scale, room-temperature preparation of high-aspect-ratio, single-crystalline Tb-doped CePO(4) nanowires, measuring approximately 12 nm in diameter and over 10 mum in length. Moreover, we also isolated sheaf-like bundles of nanostructures. The synthesis mechanism likely involved a crystal splitting step. The resulting nanowires demonstrated an intense redox-sensitive green photoluminescence, which was exploited, in addition to their inherently high biocompatibility and low toxicity, for potential applications in biological imaging and labeling of cells.
一种简单有效的模板介导法被开发出来，用于在室温下大规模制备高纵横比、单晶Tb 掺杂 CePO4 纳米线，其直径约为 12nm，长度超过 10μm。此外，我们还分离出了束状的纳米结构。该合成机制可能涉及到晶体分裂步骤。所得纳米线表现出强烈的氧化还原敏感的绿色光致发光，除了固有的高生物相容性和低毒性外，还可用于生物成像和细胞标记等潜在应用。
