Abstract

Core-shell structured luminescent materials, specifically SiO₂@YPO₄:Eu³⁺ and SiO₂@YPO₄:Eu³⁺,Tb³⁺, were synthesized by a combination of coprecipitation and high temperature solid-state methods. Structural characterization confirmed that tetragonal YPO₄ -coated the SiO₂ cores. When excited at 395 nm, the Eu³⁺-doped material exhibited dominant ⁵D₀ → ⁷F₁ emission at 593 nm. Codoping with Tb³⁺ enabled near-white light modulation, indicating potential for WLED applications.

稀土掺杂磷酸盐包覆二氧化硅核壳结构的制备及其发光性能

采用共沉淀法和高温固相法合成了核壳结构发光材料SiO2@YPO4:Eu3+和SiO2@YPO4:Eu3+，Tb3+。结构表征证实了sio_2岩心包覆有四边形的YPO4。当在395 nm处激发时，Eu3+掺杂材料在593 nm处表现出5D0→7F1的优势发射。与Tb3+共掺杂可实现近白光调制，表明WLED应用的潜力。

期刊介绍： Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry. Luminescence also publishes details of forthcoming meetings, information on new products, and book reviews. A special feature of the Journal is surveys of the recent literature on selected topics in luminescence.
