This invention discloses nanoparticles that enhance the near-infrared II fluorescence of indocyanine green, their preparation method, and applications. The nanoparticles are prepared by mixing PLGA-PEG-PLGA and ICG-NHS. The specific method is as follows: S1, dissolve PLGA-PEG-PLGA in a solvent to form a first solution; S2, dissolve ICG-NHS in a solvent to form a second solution; S3, thoroughly mix the first and second solutions, react them, and remove unreacted substances by ultrafiltration to obtain the nanoparticles. The order of steps S1 and S2 is not limited. This invention enhances the emission of ICG through PLGA-PEG-PLGA, extending the application of ICG in the near-infrared II region to the NIR-IIa region (1300nm-1400nm), and effectively prolongs the circulation time of ICG in the blood, thus removing limitations in its application in fields such as tumor and vascular disease diagnosis.

A class of metal halide-based metal-organic frameworks (MOFs) materials with multicolor tunable long-lasting emission and white light properties were synthesized by self-assembly of 15-crown ether-5 (CE) ligands and metal halide salts (CdX2), resulting in three complexes (15-5-CdCl2, 15-5-CdBr2, and 15-5-CdI2). In the solid state, the complexes (15-5-CdCl2, 15-5-CdBr2, and 15-5-CdI2) all exhibited near-standard white light emission under 340 nm ultraviolet radiation at room temperature, with CIE coordinates of (0.28, 0.32), (0.31, 0.39), and (0.30, 0.34), respectively. Simultaneously, they exhibit excitation-dependent room-temperature phosphorescence (RTP) ranging from blue / cyan to green / yellow, with 15-5-CdCl2 and 15-5-CdBr2 exhibiting multicolor tunable and visible light luminescence (LPL) with time-resolved luminescence lifetimes as high as 1-2 seconds. Single-crystal X-ray diffraction analysis and theoretical calculations indicate that the bright LPL of 15-5-CdCl2 and 15-5-CdBr2 originates from the aggregation state induced by the 15-crown ether-5 ligand and halogen bonds. The LPL obtained in this way can be widely used in lighting and display devices, optical recording devices, biological imaging, security systems, and other fields.
