In this work, a study of iron and silver nanoparticles was carried out by Raman spectroscopy. The spectra were obtained by changing the temperature. The positions of individual spectral lines were found to determine the presence or absence of second-order phase transitions. Based on the data on the shift of spectral lines, one can also draw a conclusion about the stability of the objects of study under changing external conditions and how this affects changes in the suspensions in which they are included. Absorption coefficients were measured, and the sizes of the studied nanoparticles in aqueous suspensions were determined.
Keywords: suspensions of iron and silver nanoparticles, lubricants, Raman scattering of light, shift of spectral lines.
