Core-Double-Shell Fe2O3@SiO2@Jarosite Hybrid Nanoparticles Synthesized by Laser Ablation of Turquoise in Ethanol.

ABSTRACT: This work highlights a facile green route for the one-step synthesis of iron oxide core-double-shell nanoparticles (NPs) and aluminum phosphide (AlP) nanosheets by pulsed laser ablation of the mineral turquoise target from Nishapur in the presence of an ethanol solvent. High-resolution transmission electron microscopy, selected-area electron diffraction pattern, and field emission scanning electron microscopy (FESEM) in combination with energy-dispersive X-ray mapping revealed the formation of NPs with a typical core@double-shell structure in which crystalline α-Fe2O3 (iron oxide) formed the core, while SiO2 (quartz) and (K, H3O)Fe3(SO4)2(OH6) (jarosite) participated as the inner and outer shell, respectively. However, the application of laser ablation on the turquoise phase of the target
