论文摘要
在许多研究领域，微观区域中温度分布和热行为的精确测量至关重要。我们证明了使用钻石纳米颗粒中的氮气接种中心进行锁定的热成像。我们成功地以微尺分辨率可视化玻璃盖玻片和特氟龙中的热扩散，并推断出它们的热扩散率。通过将钻石纳米颗粒扩散到样品表面上，可以直接测量温度变化而无需任何物理接触，例如铅线，从而可以看到各种材料的微米尺度的热行为。
Precise measurement of temperature distribution and thermal behavior in microscopic regions is critical in many research fields. We demonstrate lock-in thermography using nitrogen-vacancy centers in diamond nanoparticles. We successfully visualize thermal diffusion in glass coverslip and Teflon with micrometer resolution and deduce their thermal diffusivity. By spreading diamond nanoparticles over the sample surface, temperature variation can be measured directly without any physical contact, such as lead wires, making it possible to visualize the micrometer-scale thermal behavior of various materials.
