CaGd_3F_(11):Eu~(3+) nanocrystals with the morphologies of nanoparticles were prepared by octylamine and oleic acid as capping ligands,and anhydrous calcium chloride,rare earth nitrate,n-octanol as the raw materials with solvothermal method.The products were characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM)and fluorescence spectrophotometer.The results indicate that CaGd_3F_(11) nanocrystals are well-crystallized and their sizes are uniform(about 5 nm).As a luminescence host,it s...
