| 英文摘要 | The development of photothermal therapy (PTT) agents possessing temperature self-response ability and working in the deep tissues is an urgent need for noninvasive cancer treatment. Herein, a nanocomposite material hexagonal phase NaLuF4: Yb3+/Nd3+@SiO2@Cu2S is successfully constructed for the purpose of meeting the above demands. Under the irradiation of 980 nm near-infrared (NIR) light, the prepared nanocrystals (NCs) exhibit good photothermal conversion capacity and ultrasensitive temperature sensing properties along with remarkable resolution. The optical thermometry is realized by the fluorescence intensity ratio of Nd3+: 4Fj (j = 7/2, 5/2, and 3/2) levels, of which the NIR emission intensities are strongly enhanced with the increasing temperature due to the phonon-assisted energy transfer mechanisms between Yb3+ and Nd3+. As the excitation and emission wavelength of the sample are all located in the biological window, its penetration depth in the biological tissues can be reached to 8 mm. The adsorptive Cu2S NCs on the surface of NaLuF4: Yb3+/Nd3+@SiO2 provide the required light-to-heat conversion capacity, which has been investigated in detail through the laser-irradiated and bactericidal experiment respectively. These findings provide a feasible strategy to design high-performance PTT agents integrated with precise temperature self-measurement function for deep-tissue therapy. © 2023 Elsevier Ltd and Techna Group S.r.l. |
