摘要

稀土掺杂上转换发光材料的发光特性不仅依赖于基质材料本身, 而且与其激发条件密切相关. 本文主要是以Ho³⁺离子为研究对象, 在NaYF₄和LiYF₄这两种不同的基质中, 研究其在不同激发条件下的上转换发光特性. 通过共聚焦显微光谱测试系统, 对比Ho³⁺离子在NaYF₄和LiYF₄微米晶体中的发光特性. 实验结果发现: Ho³⁺离子在这两种不同基质中均展现出较强的荧光发射. 然而, 当激发功率增加时, 在单颗粒NaYF₄微米晶体中, Ho³⁺离子展现出了红白色荧光发射, 即展现出较强的红光、绿光及蓝光发射. 然而, 在单个LiYF₄微米晶体中, 当激发功率增加时, Ho³⁺离子则发射出较强绿光及微弱的红光, 红绿比变化并不明显, 其蓝光发射强度也相对较弱. 当激发这两种微米粉末晶体时, 结果发现: Ho³⁺离子均发射较强的绿光发射并伴有微弱红光发射, 两种晶体中的发射特性极其相似. 由此可见, 在常规测试条件下, 一些特殊发光现象是很难被观测到的. 同时, 通过对其光谱特性的分析, 对Ho³⁺离子的发光机理进行了研究.

Abstract

The upconversion (UC) emission properties of rare-earth ions are not only dependent on the host materials, but also relate to the excitation conditions. In this work, taking the Ho³⁺ ions for example, upconversion emission properties are studied in two NaYF₄ and LiYF₄ fluoride microcrystals through changing excitation conditions, namely the excitation power and the sample environment. The NaYF₄:20%Yb³⁺/2%Ho³⁺ and NaYF₄:20%Yb³⁺/2%Ho³⁺ microcrystal are synthesized by the hydrothermal method. The typical X-ray diffraction patterns of NaYF₄:20%Yb³⁺/2%Ho³⁺ and LiYF₄:20%Yb³⁺/2%Ho³⁺ microcrystal indicate that the prepared samples possess pure hexagonal phase NaYF₄ structure and the pure tetragonal phase LiYF₄ structure with high crystallinity, respectively. Most of NaYF₄:20%Yb³⁺/2%Ho³⁺ microcrystals show uniform and regular rod shape with diameter and length of approximately 3 μm and 10 μm, respectively. Few rods with a length of approximately 5 μm are also observed. The LiYF₄:20%Yb³⁺/2%Ho³⁺ microcrystals are all octahedral in shape with a smooth surface, the average size is around 10 μm. The spectral peculiarities of Ho³⁺ are investigated by using confocal microscopy equipment under near infrared 980 nm excitation. Beautiful patterns with different upconversion emissions of Ho³⁺ are discovered in single NaYF₄ and LiYF₄ microcrystal. As the excitation power increases, the upconversion emission of Ho³⁺ turns from green to pink in single NaYF₄ microrods due to the cross-relaxation between Ho³⁺ and the energy back transfer from Ho³⁺ to Yb³⁺. However, in single LiYF₄:Ho³⁺ microcrystal no similar phenomenon is observed. Nevertheless, when the powder of NaYF₄ and LiYF₄ microcrystals are excited by a 980 nm laser, increasing the power can turn the output colours of Ho³⁺ all green. Because particles outside the laser radiation are not directly covered by the laser, most of them are excited by the scattered light from the laser, and the actual excitation energy is low compared with at the center position. This result can be proved in the single NaYF₄ and LiYF₄ microcrystal under low excitation power. Thus, the results indicate that UC emission of rare-earth ions is controlled by changing the excitation condition. Using the new testing methods we can not only observe more interesting spectral phenomena, but also find a new way to further study its luminescence mechanism.
