Nonlinear optical and magnetic properties of BiFeO3 harmonic nanoparticles

Abstract: Enhanced magnetic behavior, exchange bias effect, and dielectric property of BiFeO3 incorporated in (BiFeO3)0.50 (Co0.4Zn0.4Cu0.2 Fe2O4)0.5 nanocomposite AIP Advances 4, 037112 (2014) Second Harmonic Generation (SHG) from BiFeO 3 nanocrystals is investigated for the first time to determine their potential as biomarkers for multiphoton imaging. Nanocrystals are produced by an auto-combustion method with 2-amino-2-hydroxymethyl-propane-1,3-diol as a fuel. Stable colloidal suspensions with mean particle diameters… Show more

“…We have shown recently their potential in the context of advanced non-linear optical imaging. 37 Recently BFO-NP were employed in vitro in a pilot study where they proved to be able to locally induce DNA damages by deep UV generation. 12 The cytotoxicity, haemolytic response and internalization mechanisms evidence here reported for coated BFO-NP suggested good biocompatibility and a great potential Figure 5.…”

“…These works were mainly motivated by the specific multiferroics properties of bismuth ferrite. However, in terms of magnetic properties, the response of pure BFO is too weak [34] for being competitive with commonly employed magnetic nanoparticles (e.g. iron oxide NPs) in health-care applications [36].…”

“…Finally BFO nanoparticles have been prepared by different methods including solvent evaporation [32], microwave hydrothermal conditions [33], combustion [34], and decomposition of glyoxylate precursor [35]. These works were mainly motivated by the specific multiferroics properties of bismuth ferrite.…”

“…For example, in one study [19] values of Ms between 0.4 and 0.09 emu/g for particles between 4 and 40 nm were found, while in another one [20] values of Ms between 1.55 and 0.35 emu/g for particles between 14 and 245 nm were measured. Other studies report Ms of 0.41 emu/g for particle size of 77 nm [24], of 0.04875 emu/g for particles of 43 nm [41] and of 3.5 emu/g for particles between 100-200 nm [42]. All these nanoparticles were practically isolated from each other, with no interface between them, which makes the surface effects more prominent.…”
