Laser-assisted Control of Bismuth Doping in Magnetic Nanoparticles
Original language description
The fine control of mono- or bi-metallic nanoparticles‘ (NPs) chemical composition is one of the most critical concerns in nanomaterial manufacturing; however, when metals holding dissimilar characteristics form bimetallic NPs, this becomes an unresolved matter. Herein we present the successful control of doping two different magnetic elements - nickel and iron- into bismuth to produce magnetic NPs with optical characteristics of semiconductors. For this, we have employed reactive laser ablation in liquids (RLAL) employing a magnetic foil (either nickel or iron) as the ablation target, which was immersed in an acetone solution with a hard-to-dissolve Bi(NO3)3 salt. The employment of various Bi(NO3)3 concentrations showed that values between 0.01 and 1 mM are optimal for manipulating the doping degree on the NPs, which was verified by scanning electron microscopy. Moreover, their magnetic manipulation testing and inspection by ultraviolet-visible spectroscopy allowed assessing that the magnetic NPs formed by Bi doping of Fe display the most appropriate optical properties towards the material exploitation in photocatalysis. Furthermore, the minimal Bi salt employment resulted in chemical waste suppression verified by inductively coupled plasma spectroscopy. Since room conditions and no hazardous reducing agents were required for this synthetic procedure, the introduced alternative represents an up-and-coming practice for producing magnetic NPs doped by Bi.
