2D rare earth (RE) materials have received considerable attention in recent years due to the fascinating luminescence, magnetism, and electric properties originated from RE associated with sharp and various emission peaks, intrinsic 2D ferromagnetism, and incommensurate charge density wave. These materials might open up a new prospect in next‐generation lighting, magnetic devices, and phototransistors. Herein, a comprehensive review of 2D RE materials is presented, focusing on their recent progresses. First, the crystal structures of 2D RE materials are discussed. Then, typical synthesis methods such as mechanical exfoliation, molecular beam epitaxy, pulsed laser deposition, and chemical vapor deposition are introduced. Furthermore, various properties in luminescence, magnetism, and electronics are summarized. The recently reported RE‐based 2D novel photodetectors are outlined as three constructions: MoS2/RE, graphene/RE, and perovskite/RE, which show promising applications for both narrow and broad band detection arised from the special absorption windows of different RE elements. Finally, the conclusions and outlook of this area are proposed, such as exploring novel 2D RE compounds, improving stability, and broadening applications.

Fluorescence (FL) imaging and photodynamic therapy (PDT) are popular in the diagnosis and treatment of diseases, respectively, especially in cancer. The excitation of the laser in the second near‐infrared (NIR‐II) window can effectively avoid the interference of spontaneous fluorescence and light scattering of tissues, obtaining high‐resolution images at deeper penetration depth. Due to their ideal spectral absorbance and high conversion efficiency, nanomaterials with emission at NIR‐II window not only overcome the absorption or emission of NIR‐II light by endogenous biomolecules, but also facilitate NIR‐II FL imaging and the application of photodynamic therapy (PDT). The research progress of NIR‐II nanomaterials for FL imaging and PDT in recent years is reviewed. First, the NIR‐II FL imaging of several representative organic and inorganic materials is introduced, including their remarkable properties and synthesis methods. Then, the use of NIR‐II nanomaterials in PDT, such as NIR‐II FL imaging‐guided PDT, and PDT combined with photothermal therapy is described. Finally, some critical challenges and open problems are proposed that need to be addressed in synthetic technology and clinical application.

“…To address the above issues, researchers developed near-infrared (NIR) responsive materials over the last two decades, thus enabling NIR light with deep tissue penetrating and minimal photo damaging characteristics to activate biomolecules [29][30][31][32][33]. As a type of popular NIR materials, upconversion nanoparticles (UCNPs) absorb 980 nm light and emit invisible/ultraviolet light, which serves as the in situ light source for light-responsive materials in deep tissue.…”

Synergistic therapy combines multiple therapeutic approaches in one shot, thus could significantly amplify the therapeutic effects. However, how to design the desirable combination to maximize the synergistic effect is still a big challenge in cancer management. Herein, a nanoagent composed of glucose oxidase (GOx) and upconversion nanoparticles (UCNPs) were constructed for programmable starving-photodynamic synergistic cancer therapy through cascade glucose oxidation and hydrogen peroxide photolysis. In this nanoagent, GOx modulated the tumor glucose metabolism and consumed the β-D-glucose to produce H 2 O 2. The glucose depletion induced "starvation" in cancer cells and caused cell death. Afterwards, the generated H 2 O 2 was photolyzed by the invisible ultraviolet emission of UCNPs under near-infrared light excitation at 980 nm. The toxic hydroxyl radicals produced by photolysis further induced cancer cell death. Both in vitro and in vivo experiments confirmed that this starving-photodynamic synergistic therapy significantly outran any single therapy. This study paves an avenue to design programmable starving-photodynamic synergistic therapy for cancer management.
