ABSTRACT
摘要

Rare earth doped/codoped phosphors have been extensively studied for different types of applications based on their intense luminescence features. For this, researchers have tried to choose the inorganic host matrices having both a low phonon cut-off frequency and a high refractive index. Many articles have been published on oxide based phosphor materials, but due to their high cut-off phonon frequency, use of these materials is restricted for optical based applications. This is why additional research has been carried out on fluoride based host materials because of their low phonon frequencies, low composition degradation, and high quantum efficiency. In this paper, the authors review the rare earth fluoride based host nano- and micromaterials for different applications and discuss possible mechanisms.

        稀土掺杂/共掺杂磷光体基于其强烈的发光特征已经在不同类型应用中进行了广泛研究。为此，研究人员试图选择了具有低声子截止频率和高折射率的无机主体基质。针对基于氧化物的磷光体材料的文章已经发表了许多，但由于它们的高截止声子频率，这些材料的使用受到基于光学应用的限制。这就是为什么对基于氟化物主体材料进行了特别的研究，因为它们的声子频率低，成分降解率低，量子效率高。在本文中，作者回顾了基于稀土氟化物的主体纳米和微米材料的不同应用，并讨论了可能的机制。
