Nanoscale optical thermometry is a promising noncontact route for measuring local temperature with both high sensitivity and spatial resolution. In this work, we present a deterministic optical thermometry technique based on quantum emitters in nanoscale hexagonal boron nitride. We show that these nanothermometers show better performance than homologous, all-optical nanothermometers in both sensitivity and the range of working temperature. We demonstrate their effectiveness as nanothermometers by monitoring the local temperature at specific locations in a variety of custom-built microcircuits. This work opens new avenues for nanoscale temperature measurements and heat flow studies in miniaturized, integrated devices.
纳米尺度光学测温法是一种很有前景的非接触式方法，可用于高灵敏度和高空间分辨率地测量局部温度。在这项工作中，我们提出了一种基于纳米级六方氮化硼中量子发射器的确定性光学测温技术。我们表明，这些纳米温度计在灵敏度和工作温度范围方面均比同类全光学纳米温度计表现更佳。通过监测各种定制微电路中特定位置的局部温度，我们证明了它们作为纳米温度计的有效性。这项工作为小型化集成设备中的纳米尺度温度测量和热流研究开辟了新途径。
