Near-infrared afterglow luminescent inorganic nanomaterials (NIR-ALINs) possess the unique property of continuing to emit near-infrared (NIR) luminescence after excitation ceases. They demonstrate excellent photostability, deep tissue penetration, and high imaging signal-to-noise ratio (SNR). Additionally, NIR-ALINs can be re-excited in vivo using visible (Vis), NIR light or X-rays, which avoids need for continuous situ excitation, thus eliminating autofluorescence biological tissues reducing tediousness multiple injections. These features make particularly attractive applications. In recent years, a series with prolonged time enhanced intensity have been discovered. However, development still faces significant challenges, as their performance is usually insufficient satisfy practical There lack systematic analysis strategies regulation nanomaterials. This review highlights rational design modulation NIR-ALINs, focusing on host substrate selection, trap engineering surface modification. Moreover, applications bioimaging, bio-detection disease therapy are summarized. Finally, present challenges perspectives applications, such properties unclear biosafety, also discussed.

Lanthanides are widely codoped in persistent luminescence phosphors (PLPs) to elevate defect concentration and enhance efficiency. However, the deleterious cross-relaxation between activators lanthanides inevitably quenches luminescence, particularly heavily doped phosphors. Herein, we report a core-shell engineering strategy minimize unwanted but retain charge trapping capacity of by confining core shell, respectively. As proof concept, prepared series ZnGa2O4:Cr, Ln (CD-Ln, = Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb) structured ZnGa2O4:Cr@ZnGa2O4:Ln (CS-Ln) nanoparticles. First-principles investigations suggested that lanthanide doping elevated electron trap for enhancing energy transfer (ET) from Cr3+ Ln3+ ions quenched luminescence. The spatial separation CS-Ln nanoparticles suppressed ET Ln3+. Due efficient suppression ET, optimal was 50 times compared CD-Ln. Moreover, intensity CS-5%Ln up 60 original ZnGa2O4:Cr. displayed significantly improved signal-to-noise ratios bioimaging. Further, interfaced with lycopene-producing bacteria Rhodopseudomonas palustris solar-to-chemical synthesis, lycopene productivity increased 190%. This work provides reliable solution fulfill potential can further promote applications biomedicine synthesis.
