Transmission electron microscopy (TEM) images show monocore structure and mean iron core sizes of approx. 5–7 nm for VSOP (a), Eu-VSOP-4 (b), and Eu-VSOP-7(c). Selected areas of electron diffraction (SAED) pattern (df) confirms the magnetite/maghemite structure and percentage of IONP as distributed by size (gi). Scale bar ac: 20 nm; scale bar df: 2 nm−1
