Synthesis of Poly(acrylic acid)-Functionalized La<sub>1-<i>x</i></sub>Eu<sub><i>x</i></sub>F<sub>3</sub> Nanocrystals with High Photoluminescence for Cellular Imaging
Abstract:Monodisperse La1 −x EuxF3 nanoparticles (NPs) were functionalized by poly(acrylic acid) (PAA) via a one-pot modified hydrothermal method. The morphology, crystal structure, surface groups, and luminescence properties of the as-produced La1 −x EuxF3@PAA NPs were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and photoluminescence (PL) spectroscopy. The produced nanoparticles were (7 ± 3) nm in size, water soluble, and buffer stab… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
