Химический синтез золотых наночастиц: механизмы образования и контроль морфологии

In this work, gold nanoparticles were synthesized by two methods: the Turkevich–Frens method and seed-mediated growth method. The features of each method and their effect on the size, morphology, and optical properties of the obtained particles are described. The dependence of the plasmon resonance wavelength on the shape of nanoparticles has been analysed using optical spectroscopy. It has also been shown that changes in synthesis conditions affect the spectral characteristics of colloidal gold
