Silver sulfide nanocrystals (Ag2S NCs) with second near-infrared (NIR-II) emission and excellent biocompatibility hold great attraction for in vivo imaging. However, current Ag2S NCs suffer severely low photoluminescence quantum yields (PLQYs), limiting the penetration depth. Herein, based on computational prediction, we proposed a facile synchronous passivation strategy employing non-toxic MgCl2 as passivator simultaneous Mg-doping chlorination of (Syn-Ag2S). Spectroscopic studies including femtosecond transient absorption measurement (fs-TAS) temperature-dependent PL spectra revealed that syn-passivation successfully enlarged nonradiative activation energy reduced defect states exciton-photon interaction, thus resulting record high absolute PLQY 46 ± 2% at 1220 nm among toxic-element-free NIR-II probes. The boosted unlocks potential deep lymph node profile lumbar nodes was clearly distinguished by Syn-Ag2S, while clinical indocyanine green (ICG) failed to do so. This also establishes an approach developing other ultrabright used not only bioimaging but photovoltaics LEDs.

Silver chalcogenide (Ag2X, X = S, Se, Te) semiconductor quantum dots (QDs) have been extensively studied owing to their short-wave infrared (SWIR, 900-2500 nm) excitation and emission along with lower solubility product constant environmentally benign nature. However, unsatisfactory photoluminescence yields (PLQYs) make it difficult obtain optoelectronic devices high performances. To tackle this challenge, researchers made great efforts develop valid strategies improve the PLQYs of SWIR Ag2X QDs by suppressing nonradiative recombination excitons. In Perspective, we summarize significant approaches heteroatom doping surface passivation enhance QDs, conclude application in high-efficiency devices. Finally, examine future trends promising opportunities regard optical properties optoelectronics. We believe that Perspective will serve as a valuable reference for advancement synthesis QDs.

Abstract Modern radiotherapy frequently employs radiosensitizers for radiation dose deposition and triggers an immunomodulatory effect to enhance tumor destruction. However, developing glioma‐targeted sensitizers remains challenging due the blood–brain barrier (BBB) multicomponent instability. This study aims green‐synthesize transferrin–bismuth nanoparticles (TBNPs) as biosafe X‐ray absorption by tumors stimulate immune response glioma therapy. The proposed protein‐based strategy provides TBNPs with BBB‐crossing ability prevents off‐target toxicity. Cellular experiments following 4 Gy of irradiation reveal that increase DNA damage in cells trigger immunomodulation, thereby inducing immunogenic cell death. Furthermore, effectively inhibit growth through synergistic immunotherapy orthotopic mouse model. findings highlight promising effective immunomodulation.
