| 英文摘要 | Accurate and real-time temperature detection is an urgent requirement in photothermal therapy (PTT). In this work, the CaSc2O4: Nd3+ nanorod with an average length of 150 nm has been determined to be an outstanding optical thermometer based on the fluorescence intensity ratio (FIR) of thermally coupled Stark sublevels of Nd3+: 4F3/2 -> 4I11/2 transition, of which the excitation and emission wavelength are located in the first and second biological window respectively, resulting in an 8 mm penetration depth in the biological tissues. The maximal absolute sensitivity and relative sensitivity as well as the minimal temperature resolution of the present sample is 0.0008 K-1, 0.0018 K-1 and 0.19 K respectively, which is superior to the vast majority of the same type ther-mometers. Besides that, the nanorods show a 7 K temperature increment after 180 s' 808 nm-laser radiation, revealing its photothermal conversion capacity thanks to the considerable nonradiative relaxation processes among the metastable energy levels of Nd3+. These results indicate that Nd3+ single-doped CaSc2O4 nanorods can be utilized as the optical thermometer in the deep-tissue PTT process for real-time thermometry along with the function of light-to-heat conversion. |
