| 中文摘要: |
| 近红外光谱检测技术具有非侵入性、便携性、响应速度快、效率高等特点，在食品分析、医学监测、虹膜识别和红外成像等领域具有广阔的应用前景。然而，近红外荧光材料面临发射谱带窄、热稳定性差的问题，极大制约了近红外器件的发展。为此，蓝光激发Cr3+掺杂的近红外发光材料在众多方案中优势显著。本综述总结了近年来Cr3+掺杂的宽带近红外荧光材料的最新研究成果，分析了Cr3+掺杂的近红外荧光材料量子效率、发射谱带、电声耦合效应和NIR pc-LED器件的封装，并阐述了Cr3+离子格位占据、敏化发光、发射谱带和热稳定性调控策略。最后，对高效宽光谱发射近红外发光材料的应用前景进行了展望。 |
| 英文摘要: |
| Near-infrared spectroscopy detection technology has the characteristics of non-invasive, portable, fast response, high efficiency, etc., and it has broad application prospects in the fields of food analysis, medical monitoring, iris recognition and infrared imaging. However, the development of near-infrared device is greatly restricted due to the narrow emission band and poor thermal stability of near-infrared phosphors materials. For this reason, blue light excitation Cr3+ doped near infrared luminescent materials have significant advantages in many schemes. In this paper, the latest research results of Cr3+ doped wideband near-infrared fluorescent materials in recent years are summarized, and the quantum efficiency, emission band, electroacoustic coupling effect and the packaging of NIR pc-LED devices of Cr3+ doped near-infrared phosphors materials are analyzed. The regulation strategies of Cr3+ ion site occupancy, sensitization and luminescence, emission band and thermal stability are described systematically. Finally, the application prospects of high-efficiency broad-spectrum emission near-infrared luminescent materials is prospected. |
