摘要:

荧光转换型近红外发光二极管(NIR pc-LED)具有体积小、谱带宽和峰位易调谐等优点,是新一代NIR光源发展的前沿,其关键在于研发可被蓝光有效激发的高效率宽带近红外荧光粉。 面向广泛研究的Cr3+激活近红外发光材料,本文综述了发射峰在800~900 nm波段材料发展现状。 基于磷酸盐、硼酸盐和硅锗酸盐等体系,阐述了其结构特征与近红外发光峰位、谱带宽度的关系,以及采用工艺优化、组分调节和共掺杂等方法调控近红外发光效率、热稳定性能的效果。

Abstract:

Near-infrared phosphor-converted light-emitting diodes (NIR pc-LEDs) are expected to be the next-generation NIR light sources, with the advantages of small size, broad bandwidth, and easy tuning of emission peaks. The key for NIR pc-LEDs is to develop highly efficient broadband NIR phosphors that can be effectively excited by blue light. Cr3+-activated NIR phosphors have been widely studied, and this paper reviews the development of Cr3+-doped NIR phosphors peaked at 800~900 nm. Based on phosphates, pyroxenes, and other systems, the relationships between the structure and the emission peak and bandwidth are summarized. Furthermore, to enhance the NIR performance, strategies of synthesis technology optimization, components design, and co-doping sensitizers are discussed in detail.

Key words: Near-infrared phosphors, 800~900 nm, Cr3+, Yb3+, Phosphates, Borates, Pyroxenes
