Rare-Earth-Doped Phosphors and Ceramics for Solid-State Lighting, Sensing, and Plant Growth
This community designs inorganic materials that emit specific colors of light when excited, primarily for use in LED lighting, temperature sensing, and horticultural illumination.
The research focuses on synthesizing and characterizing phosphors, transparent ceramics, and single crystals doped with rare-earth ions like europium and chromium. Key recurring themes include the development of red-emitting and white-light materials for solid-state lighting, the study of energy transfer mechanisms to optimize efficiency, and the engineering of thermal stability for high-power applications. A significant portion of the work addresses persistent luminescence for anti-counterfeiting and optical storage, as well as the specific spectral requirements for plant growth lighting. The materials are often structured as double perovskites, garnets, or apatites, with a strong emphasis on correlating crystal structure with optical performance.
The community is most heavily represented in research on Europium, accounting for 9.1% of all tracked Europium papers, and Yttrium, contributing 5.4% of Yttrium research. It also holds a 2.2% share of Strontium studies.
The community comprises 45,021 papers, published predominantly in the Journal of Luminescence, Journal of Alloys and Compounds, and Optical Materials.
Recent work continues to refine near-infrared emitting garnet phosphors for high quantum efficiency and explores novel double-perovskite structures for lighting applications, alongside investigations into stimuli-responsive luminescent elastomers and thermometric properties of apatite phosphors.
