摘要

Novel core-shell LaF_3: Eu~(3+) nanocrystals/PNIPAM nanogels were prepared by surface-initiated living radical polymerization. The microstructure and performance of the LaF_3: Eu~(3+) nanocrystals and the hybrid nanogels were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectrometer (XPS), and photoluminescence (PL). The thermosensitive fluorescence behaviors of the core-shell nanogels and the drug release behaviors were investigated by PL at various temperatures. The results suggested that the fluorescence performance of the nanogels was influenced greatly by the ambient temperature, either content of Aspirin absorbed in the nanogels. Compared to other reported systems, our discovery could tell how much the nanogels contain Aspirin by detecting the fluorescence intensity.
