We studied the optical properties of coated iron and its oxide (s) nanoparticles as core and silver/gold as shell materials because of their fascinating properties in tissue engineering, cancer therapy, and information storage. The maximum absorption peaks for Fe, FeO, Fe2O3 and Fe3O4 are found at 421 nm, 1500 nm. 1169 nm and 1100 nm with Ag coating, and 530 nm, 1507 nm, 1115 nm and 1200 nm with Au coating. Furthermore, the larger absorption efficiency has been found at 16 nm Ag/Au shell thickness of all considered core-shell nanostructures and especially absorption efficiency gradually increases for entire considered Au shell thickness. The largest LSPR is found for Fe2O3-core with Ag and Au-shell. It is found that the absorption LSPR spectra which are almost fixed for coated iron and varied for coated iron oxides, shows the tunability in the visible and NIR region respectively with increasing shell thickness. The LSPR peaks in visible and NIR region of electromagnetic spectrum opens the door to photonic-magnetic nanodevices, and therapeutic applications.
