此外结合生产实践提出了控制多余物的相应措施，研究结果对于红外探 测器组件的设计和工程应用具有一定指导意义。

The key for NIR pc-LEDs is to develop highly efficient broadband NIR phosphors that can be effectively excit‐ed by blue light. LiScSi2O6∶Cr3+can be excited by blue light and emits NIR light peaked at 845 nm with a broad band‐width of 156 nm and an internal quantum efficiency of 64.4%. Herein， Sc3+ is replaced by M ions （M = Ga3+， Lu3+，Y3+， Gd3+） to regulate the NIR luminescence. The introduction of M ions is easy to form heterogeneous phases or un‐dergo phase transformation， thus reducing the NIR luminescence of the titled material. The regulation processes are analyzed based on the crystal structure.Key words：LiScSi2O6∶Cr3+； cation substitution； crystal structure1 引 言近红外光谱技术具有无损伤、穿透性好等优点，在无损检测、食品安全、夜视与医疗成像等领域具有广泛应用[1-5]。

自由曲面在离轴反射式空间光学成像系统中的应用朱钧;吴晓飞;侯威;杨通;金国藩【摘要】In the field of space optics which is closely related to aeronautics and astronautics, off-axis reflective imaging systems are attracting more and more researchers’ attention due to their various advantages. Compared with traditional spheres and aspheres, freeform surfaces have higher degrees of design freedom, and are capable of correct a variety of asymmetric aberrations. Therefore, freeform surfaces have full capability of designing the off-axis reflective imaging systems, and furthermore they have the potential to meet some high-end or special requirements in space optics. Improving optical performance and realizing special structure are two main application directions of freeform surfaces in space optics. In this paper, following the two directions and aiming at some real requirements of space optical imaging systems, including low F-number, wide field-of-view, compact structure, having a real exit pupil and afocal system, the authors have selected several representative freeform off-axis reflective imaging systems, and emphatically introduced their system configurations, optical performance, and application advantages in space optics.%在空间光学领域，离轴反射式成像系统凭借其多方面的应用优势，正愈发引起研究人员的关注与开发。
