A research team led by Professors Xu Shuhong and Wang Chunlei from the School of Electronic Science and Engineering at Southeast University has recently published groundbreaking findings in the journal SCIENCE CHINA Chemistry. The article, titled "Carbon Dots@Homogenous Matrix Composite with Room-Temperature Phosphorescence via Controllable-Carbonization Technology," represents the sole contribution from Southeast University. The study introduces a novel carbon dot@homogeneous matrix composite material that exhibits both solid-state fluorescence and room-temperature phosphorescence properties.

Room-temperature phosphorescent materials hold significant promise for applications in information security, optoelectronic devices, and bioimaging. However, traditional materials in this field have been hampered by issues such as high toxicity, exorbitant costs, complex purification processes, and insufficient stability. Carbon dots, on the other hand, offer a promising alternative due to their low toxicity, straightforward preparation, cost-effectiveness, and tunable optical properties.

Through a meticulously controlled carbonization strategy, the research team successfully constructed a carbon dot-homogeneous matrix system. This system enables more efficient room-temperature phosphorescence emission, thereby offering fresh perspectives for the ongoing research and application of room-temperature phosphorescent materials.
