Special Issue Information

Dear Colleagues,

Luminescent materials have emerged as an essential class of functional materials, enabling transformative progress in diverse areas such as bioimaging, sensing, optoelectronics, and energy conversion. Their versatile emission behaviors, including fluorescence, phosphorescence, thermally activated delayed fluorescence (TADF), and room-temperature phosphorescence (RTP), offer unique opportunities for both fundamental scientific discovery and technological applications. The continued advancement in molecular design, mechanistic understanding, and device integration has established luminescent materials as a multidisciplinary field connecting chemistry, physics, biology, and materials science.

This Special Issue, “Advancements in Fluorescent Materials and Applications”, aims to showcase recent developments in the design, study, and application of luminescent materials. We welcome original research articles and reviews addressing both experimental and theoretical progress. Potential topics include, but are not limited to:

  • Molecular design and synthesis of luminescent materials: thermally activated delayed fluorescence (TADF); room-temperature phosphorescence (RTP); aggregation-induced emission (AIE);
  • Mechanistic studies of luminescent processes;
  • Fluorescent probes for bioimaging and sensing;
  • Applications in optoelectronic devices (OLEDs, light-emitting electrochemical cells, lasers, etc.);
  • Stimuli-responsive and multifunctional luminescent systems;
  • Emerging applications in photocatalysis, phototherapy, and energy-related technologies.

Carbon dots (CDs) have enormous potential in optical sensing applications due to their remarkable physicochemical properties. Benefiting from high specific surface area, rich active sites, bright photoluminescence, high photostability, and biocompatibility, CDs have been widely used as functional layers in optical fiber sensors, resulting in notable improvements in sensitivity, response speed, and environmental stability. This review describes recent advances in CD-integrated optical fiber sensors, with a focus on CD synthesis techniques and their integration with optical fibers for the sensing of diverse analytes, including heavy metal ions, biomarkers, and dyes. CD-integrated fiber sensors exhibit significantly enhanced detection performance in terms of sensitivity, selectivity, repeatability, response time, and recovery time, compared with their CD-free counterparts. Finally, current challenges and future perspectives are discussed. This review aims to provide valuable insights for the design and development of novel CD-integrated optical fiber platforms for sensing chemically and biologically relevant analytes. Full article
