摘要: 稀土具有的上转换(UC)发光性能为光催化剂的发展拓宽了方向。基于稀土元素掺杂改性和稀土上转换剂复合两种功能均能体现稀土上转换性能在光催化领域的研究和应用价值,论文从以上两个方面综述稀土上转换光催化剂的研究进展。具有上转换性能的稀土元素主要有Er、Yb、Tm、Ho、Tb等,其中Yb常作为敏化剂,Er因其高效、绿色的发光性能而研究应用最为广泛。根据基质组分不同,稀土上转换剂可分为稀土氟化物、稀土卤氧化物、稀土氧化物或复合氧化物三类,其中以NaYF4等的研究较为突出。UC材料研究拓宽了光催化剂在紫外-可见-红外的全光谱响应,但由于其量子效率相对较低,UC材料的构建及研究仍需要进一步深入,本文旨在为相关人员在该领域的研究提供启发和帮助。

Abstract: The up-conversion (UC) luminescent properties of rare earth broaden the development of photocatalsyts. Rare earth elements and up-conversion agents all could promote the photocatalytic activity and research value by broadening the light response from infrared to violet irradiation in the field of photocatalytic technology. This paper reviewed the research progress of the rare earth up-conversion luminescent photocatalysts. Er, Yb, Tm, Ho and Tb are the main elements which have properties of up-conversion luminescence, of which Yb is usually taken as the sensitizing agent while Er is the most widely studied because of its efficient and green luminescent properties. According to their different structures, rare earth up-conversion agents are classified into three categories: rare earth fluoride, rare earth oxyhalide, and rare earth oxides or composite oxides. NaYF4 was studied widely because of its outstanding properties. Although the excellent properties of rare earth UC materials, there still exists some drawbacks, especially the low quantum efficiency of UC materials, which greatly limits the photocatalytic activities. Therefore, the rare earth UC photocatalysts need further construction and research. This paper intends to provide some inspiration and help for the researches in the area of full spectrum photocatlaysts.
