摘要

在这里,我们报道了一种非常灵敏、非接触、比率度量和稳健的基于发光的温度传感,该温度传感使用半导体BiFeO3(BFO)纳米线的传统光致发光(PL)和负热猝灭(NTQ)机制的组合。使用这种方法,我们已经证明了 ~ 在300–438 K温度范围内为10 mK−1,在300 K下的相对灵敏度为0.75%K−1。此外,我们还使用线性回归和层次分析法(AHP)定量验证了BFO纳米线的热敏性,并发现与实验结果非常吻合。这些结果表明,BFO纳米线是开发基于高性能发光的温度传感器的优秀候选者。图形摘要

Multiple ratiometric nanothermometry using semiconductor BiFeO3 nanowires and quantitative validation of thermal sensitivity
Here, we report a very sensitive, non-contact, ratio-metric, and robust luminescence-based temperature sensing using a combination of conventional photoluminescence (PL) and negative thermal quenching (NTQ) mechanisms of semiconductor BiFeO 3 (BFO) nanowires. Using this approach, we have demonstrated the absolute thermal sensitivity of ~ 10 mK −1 over the 300–438 K temperature range and the relative sensitivity of 0.75% K −1 at 300 K. Further, we have validated thermal sensitivity of BFO nanowires quantitatively using linear regression and analytical hierarchy process (AHP) and found close match with the experimental results. These results indicated that BFO nanowires are excellent candidates for developing high‐performance luminescence-based temperature sensors. Graphical abstract
