Rare-Earth-Doped Phosphors and Glasses for Solid-State Lighting, Sensing, and Lasers
This community develops inorganic materials that emit light when excited, primarily to power white LEDs, enable temperature sensing, and drive laser systems.
The work centers on synthesizing and characterizing borate, phosphate, and tellurite glasses, as well as transparent ceramics and single crystals, doped with rare-earth ions like europium and dysprosium. Recurring themes include optimizing energy transfer mechanisms, ensuring thermal stability, and tuning emission spectra for white light generation. Specific applications named in the literature include red phosphors for LED conversion, persistent luminescence for anti-counterfeiting, and near-infrared emission for spectroscopy. The research frequently examines the structural and optical properties of these host matrices to improve quantum efficiency and color purity.
The community is most heavily concentrated in europium research, accounting for 11.4% of all tracked europium studies, and neodymium research, representing 5.8% of that element’s output. It also forms a significant portion of yttrium research, comprising 7.9% of that element’s tracked papers.
The community comprises 75,329 papers, with the highest publication volumes in the Journal of Luminescence, Journal of Non-Crystalline Solids, and Optical Materials.
Recent work continues to focus on refining rare-earth-doped luminescent materials, including studies on structural and optical properties of borate glasses, the development of near-infrared garnet phosphors with high quantum efficiency, and the engineering of glass ceramics for full-spectrum lighting applications.
