Abstract

We demonstrate fluorescent Fe embedded magnetic nanodiamonds by ion implantation and two-step annealing. The diamond characteristics with a highly ordered core and a graphite surface layer are maintained after the implantation process. After the two-step annealing process, a bright red fluorescence associated with nitrogen-vacancy centers is observed. These new fluorescent magnetic nanodiamonds can be used as a dual-function in vivo tracer with both optical visibility and magnetic resonance imaging capabilities. They are potentially useful for the more advanced in vivo biological and medical applications.

摘要

我们通过离子注入和两步退火法制备出了荧光 Fe 嵌入磁性纳米金刚石。注入过程后，金刚石仍保持着高度有序的芯和石墨表面层的特征。经过两步退火过程后，观察到与氮空位中心相关的亮红色荧光。这些新型荧光磁性纳米金刚石可用作具有光学可见度和磁共振成像能力的双重功能体内示踪剂。它们在更先进的体内生物和医学应用中具有潜在的用途。
