In the present study, we report a fabrication of dual-mode carbon coated gadolinia C@Gd2O3 particles by a facile hydrothermal synthesis method without using any organic solvents. The prepared C@Gd2O3 particles have a core–shell structure and a narrow size distribution in the range of 261±27 nm. The fluorescent properties of the prepared C@Gd2O3 particles were accessed by a room-temperature photoluminescence study, while the longitudinal relaxivity (r1) was examined by using a clinical 1.5 T MRI scanner. A murine fibroblast L-929 cell line was used to examine the cytotoxicity and capability of the prepared C@Gd2O3 particles for the fluorescent labeling. The obtained results show that the prepared C@Gd2O3 particles could be used as a dual-mode contrast agent for magnetic resonance and fluorescence imaging.

A flower-like hematite microstructure has been successfully prepared by a facile hydrothermal synthesis method without using any organic solvents or templates. It is revealed that the flower-like hematite microstructure consists of well-crystallized nanorods with the average diameter of about 100±15 nm and average length of about 900±100 nm growing from the centers. A possible growth mechanism of the flower-like α-Fe2O3 microstructure is proposed and discussed. The photocatalytic properties of the synthesized flower-like hematite nanostructure are evaluated using the degradation of rhodamine B in aqueous solution.
