Persistent luminescent nanoparticles (PLNPs) exhibit ultralong afterglow properties due to their excellent light storage mechanism and great potential for biomedical, energy, environmental applications. However, PLNPs have certain limitations regarding photogenerated carrier separation efficiency, absorption range, specific surface area, which limit efficiency performance in practical Herein, we reported a multifunctional nanoplatform based on carbon nanotubes (CNTs) loaded with (ZnGa1.97O4:Cr0.01, Bi0.02, ZGO). Experimental characterizations density functional theory calculations showed that the combination of CNTs significantly reduced recombination carriers PLNPs, increased enhanced intensity near-infrared (NIR) region. By optimizing ratio, ZGO-10CNTs not only exhibited greatest photocatalytic activity pollutant degradation but also generating reactive oxygen species, demonstrating therapy In addition, demonstrated NIR photothermal conversion pH-responsive drug release. The integration led development capabilities degradation, therapy, delivery, thus expanding design nanoplatforms PLNPs. construction this provides new strategies cancer opens up perspectives applications energy fields.
