Note: Spectroscopy of nanowires with different Sr/Fe ratio inside the internal nanoparticles (uniform nanowires) is the presence of Fe and Sr elements caused by strontium ferrite.
In the spectroscopy of uniform nanowires, it can be seen that the ratio of Sr/Fe nanoparticles in the sample is closer to its stoichiometric value in the electromagnetic composition of nanoparticles, while due to the lower solubility of nanomolecules in uniform strontium nanowires compared to iron nitrate. and following that, the presence of less strontium ions in the reaction, with the electromagnetic particles of nanowires, more amount of Fe ions in the structure There is an end. To separate uniform nanowires, molar electromagnetic active particles are used at ambient temperature .
In general, in order to investigate the electromagnetic properties of nanowires, it is necessary to produce uniform nanowires with a specific diameter and length. Nanowires are less than 100 nm in diameter and can be as small as 3 nm. Typically, nanowires are more than 1000 times larger than their diameter. This huge difference in length-to-diameter ratio compared to nanowires is often referred to as 1D materials. This leads to unique properties not seen in bulk materials, the minute size of nanowires means that quantum mechanical effects become important. "Quantum wires" exploit quantum mechanics to produce wires with a wide range of unique electrical properties. These properties include quantum tunneling, which allows wires made of carbon nanotubes to have very high conductivity with electrons traveling ballistically through the wire.
In the immersion method, the nanowires have enough time to transfer from the particles of the nanowires to the holes; The step of forming uniform nanoparticles is done slowly and finally uniform nanowires are formed. Structural investigation with FESEM in the immersion method of uniform nanowires in all pores and in a wide area in nanowire particles.
The simple answer to this question is any particle less than 100 nanometers. But as the scale of 1-100 nm determines the size range of a nanoparticle. In order to prevent particle contact, a cluster of atoms may be removed below 1 nm, but the electron movement in nanoparticles has to particles <1 nm. Because particles are three-dimensional.
Conclusion:
Spectroscopy of nanowires with different Sr/Fe ratio inside the internal nanoparticles (uniform nanowires) is the presence of Fe and Sr elements caused by strontium ferrite.
