Summary: By studying the effect of different Yb3+ concentrations on Er3+ and Yb3+ co-doped phosphors, it was found that increasing the concentration of Yb3+ decreases the visible emission intensity of Er3+ but increases the near-infrared emission of Yb3+. Furthermore, Yb3+ can enhance the up-conversion luminescence of Er3+. The results suggest that the energy transfer between Yb3+ and Er3+ ions is reversible.

Summary: Ni2+ doped and Ni2+/Er3+ co-doped Gd2MgTiO6 (GMT) phosphors were synthesized. First-principles calculation and X-ray diffraction analysis showed that Ni2+ ions occupy Mg2+ sites at low doping concentration and Ti4+ sites at high doping concentration. The near infrared emissions of Ni2+ ions occupying Mg2+ and Ti4+ sites peak at 1344 nm and 1412 nm, respectively. Ni2+/Er3+ co-doped Gd2MgTiO6 phosphor can up-convert near infrared photons to visible emission in the range of 870-1700 nm. The Gd2MgTiO6: 2%Ni2+/5%Er3+ phosphor shows the strongest up-conversion emission, and the energy transfer efficiencies from Ni2+ to Er3+ are 81.5% and 79.3%, respectively. The phosphor exhibits yellow, green, and orange-red emissions under different laser irradiations. It has wide application prospect in anti-counterfeiting, solar cell efficiency enhancement, and infrared detection.

Summary: Photodynamic therapy (PDT) or chemodynamic therapy (CDT) based on reactive oxygen species (ROS) have been recognized for their low susceptibility to microbial resistance. However, traditional ROS treatment couldn't achieve satisfactory wound healing due to the complex biofilm structure and high quenching rate. Therefore, researchers developed Na2S2O8@ZIF-67/GOx nanoparticles as a high-toxic ROS nanogenerator for biofilm-infecting wound healing, utilizing glucose oxidase (GOx) for amplified CDT and immune activation. The NZG NPs released high-toxic ROS within the biofilm, inhibiting bacterial and biofilm proliferation and promoting immune system activation, ultimately achieving effective wound healing without bacterial tolerance.
