dc.description.abstract | Nanoparticles as contrast agents for in-vitro and in-vivo imaging is the most astounding, non-invasive method developed by researchers in the present scenario. To improve the multifunctionality of bio-imaging field, both Magnetic resonance imaging (MRI) and fluorescence based nanoconstructs are appreciated. In this regard, current research is dedicated to fabricate Fe3O4@NaGdF4 core-shell structure as a multifunctional, efficient probe to be useful for said purpose. Concerned core-shell is constructed in layer-by-layer approach with Fe3O4 as core which is prepared with precipitation method. Phase purity of sample is investigated through x-ray diffraction data, seen to have inverse spinel phased Fe3O4 core and hexagonal NaGdF4. Morphological images clarified the core-shell formation with desired dimension. Magnetic criteria of sample are studied through room temperature magnetic field dependent magnetization (M-H) data in the range of ±1.5 Tesla. Non-magnetic shell is seen to be dominate on magnetic core for reducing the magnetic saturation value (Ms) of isolated Fe3O4. Fourier Transform Infrared Spectroscopy (FTIR) data reveals the functional group associated with the corresponding components. Downconversion luminescence is also detected through photoluminescence study in the near ultraviolet range due to Gd3+ in the system. | en_US |
