| 摘要: 采用高温固相合成法制备了Er3+，Yb3+双掺杂的GdOCl荧光材料，并研究其荧光性能。该双掺杂体系荧光粉吸收紫外光，发出红色（619 nm）和近红外（~979 nm）荧光。在这些荧光材料中，1个Er3+离子可以有效将其能量转移给2个Yb3+离子。通过改变Yb3+掺杂浓度，对比Gd0.998 5-yOCl：0.0015Er3+，yYb3+中的Er3+的发射光谱和不同检测波长的荧光寿命变化特点，对Er3+-Yb3+ 发生量子剪裁的能级进行分析和指认，并计算了能量转化效率（η）和量子效率（Q）。正是由于具备这种荧光性能，该荧光材料体系有望在荧光太阳能收集器以及军事和医学的红外显示和探测技术中获得应用。 |

| Abstract: The phosphors in the system GdOCl:Er3+,Yb3+ were synthesized by solid-state reactions and their photoluminescence properties were investigated. These phosphors have absorption in the ultraviolet light region and give luminescence in the red (619 nm) and near-infrared region (~979 nm). In these phosphors, one Er3+ ion can effectively transfer its absorbed energy to two Yb3+ ions, which are suitable for the application in the device of luminescent solar concentrator (LSC) and near-infrared display. |
