Spectroscopic, structural and in vitro cytotoxicity evaluation of luminescent, lanthanide doped core@shell nanomaterials GdVO<inf>4</inf>:Eu<sup>3+</sup>5%@SiO<inf>2</inf>@NH<inf>2</inf>
Abstract
<p>The luminescent GdVO<sub>4</sub>:Eu<sup>3+</sup>5%@SiO<sub>2</sub>@NH<sub>2</sub> core@shell nanomaterials were obtained via co-precipitation method, followed by hydrolysis and co-condensation of silane derivatives: tetraethyl orthosilicate and 3-aminopropyltriethoxysilane. Their effect on human erythrocytes sedimentation and on proliferation of human lung microvascular endothelial cells was examined and discussed. The luminescent nanoparticles were synthesized in the presence of polyacrylic acid or glycerin in order to minimalize the agglomeration and excessive growth of nanostructures. Surface coating with amine functionalized silica shell improved their biocompatibility, facilitated further organic conjugation and protected the internal core. Magnetic measurements revealed an enhanced T<sub>1</sub>-relaxivity for the synthesized GdVO<sub>4</sub>:Eu<sup>3+</sup>5% nanostructures. Structure, morphology and average grain size of the obtained nanomaterials were determined by X-ray diffraction, transmission electron microscopy and dynamic light scattering analysis. The qualitative elemental composition of the nanomaterials was established using energy-dispersive X-ray spectroscopy. The spectroscopic characteristic of red emitting core@shell nanophosphors was completed by measuring luminescence spectra and decays. The emission spectra revealed characteristic bands of Eu<sup>3+</sup> ions related to the transitions <sup>5</sup>D<sub>0</sub>-<sup>7</sup>F<sub>0,1,2,3,4</sub> and <sup>5</sup>D<sub>1</sub>-<sup>7</sup>F<sub>1</sub>. The luminescence lifetimes consisted of two components, associated with the presence of Eu<sup>3+</sup> ions located at the surface of the crystallites and in the bulk.</p>
