稀土掺杂纳米晶体荧光发射性质的调控
Controlling The Fluorescence Emission of Rare Earth Doped Nanocrystals
摘要
Abstract
The fluorescence emission of rare earth doped nanocrystal depends on the optical active ion and its matrix structure. For a given system, it can be adjusted either by changing the characteristics of the particle or by improving the environmental conditions around the particle. The ebaracteris-tics of the particle can be modified by adjusting the content and structure of the matrix crystal, codopant ion and its concentration, morphology and size of the particle, surface modification as well as the introduction of enhancement through metallic surfaces. The environmental change could refer to the environmental temperature and the excitation of the system. In current paper, possible factors that influence the fluorescence emission as well as frequently used techniques for controlling the fluorescence properties are reviewed briefly. Changes in local symmetry and interactions of optically active ion with neighbored ions, which are mainly induced by adjusting the crystal structure and codoping process, are discussed intensively.关键词
