Synthesis and characterization of NaGdF4:Nd3+@Ni Core@Shell nanoparticles with potential applications in anaerobic digestion. Dig. J. Nanomater. Bios. 2023, 18(3), 1093–1103. https://doi.org/10.15251/DJNB.2023.183.10931842-358210.15251/DJNB.2023.183.1093https://hdl.handle.net/20.500.14352/132845This journal offers open access to all content and is licensed under a Creative Commons Attribution 4.0 International License..The NaGdF4:Nd3+@Ni core@shell nanoparticles were synthesized and characterized. First, core@shell nanoparticles were synthesized using a solvothermal method to obtain the NaGdF4:Nd3+ core with hexagonal phase; subsequently, a chemical reduction was performed to stimulate the growth of the Ni shell with cubic phase. NaGdF4:Nd3+@Ni nanoparticles were characterized by transmission electron microscope, zeta potential, X-ray diffraction, scattered energy spectroscopy, UV-Vis, and photoluminescence emission spectra. The nanoparticles were round in shape, with mean sizes around 250 nm. The core@shell nanoparticles presented a homogenous composition and good stability. The photoluminescent emission of the nanoparticles was recorded at 1059 nm in the near infrared spectral range; this band corresponds to the 4F3/2→4I11/2 radiative transitions of Nd3+ ions. The synthesized nanoparticles, being hydrophilic, have potential for use in different areas, one of them could be in anaerobic digestionengAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal articlehttps://doi.org/10.15251/DJNB.2023.183.1093https://www.imrpress.com/journal/DJNB/18/3/10.15251/DJNB.2023.183.1093https://chalcogen.ro/1093_AguilarMorenoGS.pdfopen access535Luminescent nanoparticlesCore-shellNear-infraredNickel nanoparticlesOptical propertiesFísica (Física)2209 Óptica
