Abstract

Fluorescent diamond particles are candidates for imaging and quantum sensing in a range of applications in biological, biomedical, and industrial fields. The fluorescence of these diamond particles originates from atomic scale defects (color centers) within the diamond lattice. Color centers in diamonds are bright and photostable. Recent advances in the synthesis and processing of diamond particles have greatly expanded the variety of available luminescent colors, making such particle suitable for multicolor imaging. Some color centers, such as the nitrogen vacancy center (NV), can exhibit several useful properties, including exceptionally long spin coherence times. The latter property has been actively exploited to manipulate NV electronic spins with magnetic fields and microwaves at resonant frequencies and then read out the spin states optically – all at room temperature. Additionally, the diamond particles themselves bring a host of additional properties, such as chemical and mechanical robustness and high biocompatibility. The combination of these properties makes fluorescent diamond particles unique among the other materials. Herein we briefly review some of the ongoing developments in the production of fluorescent diamond particles and also highlight both the recent advances and the most promising potential applications of this technology.

摘要

在生物、生物医学和工业领域的一系列应用中，荧光金刚石颗粒是成像和量子传感的候选者。这些金刚石颗粒的荧光源自金刚石晶格内的原子级缺陷（色心）。钻石的色心明亮且耐光。金刚石颗粒合成和加工的最新进展极大地扩展了可用发光颜色的种类，使这种颗粒适用于多色成像。一些色心，例如氮空位中心 (NV)，可以表现出一些有用的特性，包括特别长的自旋相干时间。后一种特性已被积极利用，以利用磁场和微波在共振频率下操纵 NV 电子自旋，然后在室温下以光学方式读出自旋状态。此外，金刚石颗粒本身还具有许多附加特性，例如化学和机械稳定性以及高生物相容性。这些特性的结合使荧光金刚石颗粒在其他材料中独树一帜。在此，我们简要回顾了荧光金刚石颗粒生产方面的一些正在进行的发展，并重点介绍了该技术的最新进展和最有前途的潜在应用 例如化学和机械稳定性以及高生物相容性。这些特性的结合使荧光金刚石颗粒在其他材料中独树一帜。在此，我们简要回顾了荧光金刚石颗粒生产方面的一些正在进行的发展，并重点介绍了该技术的最新进展和最有前途的潜在应用 例如化学和机械稳定性以及高生物相容性。这些特性的结合使荧光金刚石颗粒在其他材料中独树一帜。在此，我们简要回顾了荧光金刚石颗粒生产方面的一些正在进行的发展，并重点介绍了该技术的最新进展和最有前途的潜在应用.
