论文摘要
使用悬浮的钻石中氮呈（NV）中心的自旋特性，我们表征了单纳米座的吸收。我们首先校准了嵌入纳米原子座中的NV中心的温度响应。然后，使用此校准，我们估计单个悬浮纳米座的吸收横截面。我们表明，这种吸收是外在的，并由卷效作用主导。我们的工作为钻石材料的优化开辟了道路，以进行悬浮量子实验。它还证明了光悬浮是在纳米颗粒水平上表征材料热性能的独特平台。
Using the spin properties of nitrogen-vacancy (NV) centers in levitated diamond, we characterize the absorption of single nanodiamonds. We first calibrate the thermometry response of the NV centers embedded in our nanodiamonds. Then, using this calibration, we estimate the absorption cross-section of single levitated nanodiamonds. We show that this absorption is extrinsic and dominated by volumic effects. Our work opens the way to diamond materials optimization for levitation quantum experiments. It also demonstrates optical levitation as a unique platform to characterize material thermal properties at the nanoparticle level.
