摘要：Luminescence in the second near-infrared window (NIR-IIb, 1500-1700 nm) has garnered significant attention in bioimaging due to its advantages of deep tissue penetration and low autofluorescence. However, luminescent materials in this spectral range, particularly rare-earth nanomaterials, still face the core challenge of small absorption cross-sections leads to limited luminescence efficiency and poor dye sensitization performance. To address these issues, this study proposes a synergistic enhancement strategy. Ce3 & thorn; and Yb3 & thorn; ion doping was employed to enhance the downshifting luminescence of NaErF4based nanoparticles, while propylene glycol distearate was introduced as a morphology-directing agent to successfully fabricate NaErF4: Ce3 & thorn;, Yb3 & thorn; nanodisks via reaction-induced self-assembly. Research indicates that these uniquely structured nanodisks effectively shorten the energy transfer distance between dye molecules and rare-earth ions, thereby significantly improving sensitization efficiency. As a result, the downshifting luminescence intensity of the material in the NIR-II region was remarkably enhanced by 62.5-fold. Systematic in vivo experiments further confirmed that the as-prepared nanodisks not only exhibit excellent luminescence performance in living organisms but also possess good biocompatibility, offering new insights into material design and fabrication strategies for developing high-performance bioimaging probes.
