| Abstract: |
| Lanthanide is a metal rare-earth element； its trivalent ion （Ln3+） is prone to coordination with nitrogen and oxygen atoms due to their unique electronic layer structure， and exhibits unique fluorescence properties. The coordination of organic ligands forms high-coordination complexes with special topological structures. However， the inherent defects such as difficulty in processing and molding， accompanying side reactions， and refractory degradation limit the practical application of rare-earth coordination compound. Therefore， it is normally composited with polymer base to fabricate hybrid materials. Compared with traditional polymers， cellulose， as a new generation of hybrid matrix base materials， has the advantages of high specific surface area， degradability， renewability， and chemical modifiability， and is gradually used as the carrier for rare-earth hybrid luminescent materials. In this review， the research progress of cellulose/rare earth hybrid materials in bioimaging， medical dressings， photoelectric conversion， fluorescence anti-counterfeiting， and fluorescent probes in recent years was summarized， and its development trend was prospected. |
