Résumé
In this experiment, sodium carboxymethyl cellulose (CMC) was used as raw material, rare earth chloride was used as inorganic nano luminescent material to prepare a series of lanthanide rare earth ions-doped composite materials. The photoluminescent materials were prepared via in-situ chemical deposition of rare earth ions onto CMC surface with the help of carboxyl groups contained on the surface of CMC. The structure, fluorescence properties, surface morphology, surface elements, crystalline structure and thermal stability of CMC before and after surface modification were characterized by FT-IR spectra (FTIR), photoluminescence spectra (PL), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and thermal gravimetric analyses (TGA), respectively. The results showed that CMC/LaF
