In this paper, samples containing gold nanoparticles (NPs) distributed in different optically transparent media have been synthesized and characterized. A liquid (aqueous) and a solid (porous silicate glass and polymer (polyvinylpyrrolidone)) media were used. The samples obtained were characterized by optical spectroscopy and electron microscopy. The position of plasmon resonance band was analyzed depending on the dielectric constant of the medium.

Keywords: gold nanoparticles, colloidal solution, polymer, porous glass
