摘要：
【目的】Cr离子掺杂近红外（near-infrared, NIR）荧光材料在食品安全、医疗诊断、现代农业与环境保护等各领域广泛应用，获得研究人员的大量关注。NIR荧光材料的发射带宽对近红外光谱技术检测分析的灵敏度和检测范围至关重要，为获得Cr离子激活的超宽带NIR荧光材料，分析Cr离子的价态和晶格格位占据，理解发光构效关系，对实现新型Cr离子激活的超宽带NIR荧光材料具有重要意义。【研究现状】综述NIR荧光材料中Cr离子的常见价态，总结Cr离子掺杂超宽带NIR荧光材料的设计方法，概括不同方法制备材料的发光机制，对比不同近红外荧光材料设计方法的优缺点。【结论与展望】认为选取弱晶体场环境基质材料，进行晶格位点调控是获得高效Cr离子掺杂超宽带近红外发光材料的有效方法。
