Luminescent nano‐structured semiconductor materials via doping engineering: Functional applications toward intelligent optoelectronics and photonics

Abstract Luminescent ion‐doped materials have gained extensive attention and application in both scientific research and practical fields. The integration of luminescent ions with nano‐structured semiconductors has emerged as a highly promising development trend to meet the growing demands for advanced functional systems. This review focuses on luminescent ion‐doped nano‐structured semiconductors, including 0D, 1D, and 2D systems. It elaborates on the pivotal roles that luminescent ions play within these materials. Subsequently, the article offers a comprehensive overview of the application scenarios and effects of various luminescent ions doped into nano‐structured semiconductors. Additionally, the article systematically discusses the coupling mechanisms between luminescent ions and nano‐structured semiconductors, as well as the synergistic effects of codoping. We also present the specific applications of these materials in the information and functional materials fields. Lastly, this work addresses the current challenges faced in this research area and outlines the frontier development directions, providing valuable insights for future exploration.
