Abstract

Here we show that gradient force optical tweezers can be used to mediate the self-assembly of nanodiamonds into superstructures, which can serve as optically trapped nanoscale quantum probes with superior magnetic resonance sensing capabilities. Enhanced fluorescence rates from nitrogen-vacancy NV^– defect centers enable rapid acquisition of optically detected magnetic resonance (ODMR), and shape-induced forces can improve both positioning accuracy and orientation control. The use of confocal imaging can isolate the signal from individual nanodiamonds within the assembly, thereby retaining the desirable properties of a single crystal probe. The improvements afforded by the use nanodiamond assemblies has the potential to resolve dynamic changes through, for example, real-time monitoring of the ODMR contrast.

光镊组装纳米金刚石量子传感器

在这里，我们展示了梯度力光镊可用于介导纳米金刚石自组装成超微结构，这种超微结构可用作光学捕获的纳米级量子探针，具有卓越的磁共振传感能力。氮空位 NV 缺陷中心增强的荧光率可快速获取光学检测磁共振（ODMR），而形状诱导力可提高定位精度和方向控制。使用共焦成像技术可以隔离组件内单个纳米金刚石的信号，从而保留单晶探针的理想特性。使用纳米金刚石组件所带来的改进有可能通过实时监测 ODMR 对比度等方式来解析动态变化。
