摘　　要：石榴石基荧光材料具有多格位掺杂、离子掺杂选择范围宽、能量传递效率高等突出优势,是无机发光材料研究的热点;过渡金属离子在光谱可调谐性、原料来源广泛性等方面显著优于稀土离子;然而,其在发光效率、价态调控特别是在复杂晶格结构中的发光机理尚存在挑战,吸引了众多研究者关注。本文综述了过渡金属离子特别是Cr^(3+)、Mn^(2+/4+)在石榴石结构荧光材料中的光谱特性和发光行为,介绍了该类材料在固态照明与显示、生物医学成像、植物照明等前沿领域的研究与应用现状。Garnet-based phosphor materials have some advantages of multi-site of doping icons,a wide option of doping ions,and a high efficiency of energy transfer,thus becoming a research hotspot for inorganic luminous materials.Compared with rare-earth ions,transition metal ions have superior features of spectral regulation and low cost.However,its luminous efficiency,valence,and luminous mechanism in complex lattice structures are still unclear.This review summarized the spectral characteristics and luminescent behavior of transition metal ions,especially Cr^(2+),Mn^(2+/4+),In addition,the application of transition metal ions in the fields of solid-state lighting,displays,biomedical imaging,and plant lighting was also represented.
