Nanotechnology and nanomaterials represent a turning point in modern science. Their application leads to immense technological progress. Due to their excellent properties, nanomaterials such as nanosilver and graphene play a special role. However, their production processes can be very complicated and extremely expensive. The goal of this thesis is to obtain graphene and nanosilver by photoreduction. For this purpose, intense pulsed light (IPL) was used to reduce silver chloride and graphene oxide. As a result, silver nanoparticles and reduced graphene oxide were obtained dispersed in different solvents such as water, ethanol, N,N-dimethylacetamide (DMAc), citrate buffer with a pH value of 10, and ethanol with the addition of polyvinyl butyral (PVB) as a stabilizer. Due to its simplicity, promptitude, environmental suitability and low energy consumption, photoreduction with intense pulsed light is increasingly used as a production method of nanomaterials. The reduction efficiency was monitored with a UV/Vis spectrophotometer, and the results were presented graphically. The reduction of graphene oxide is manifested by the shift of the absorption maximum from a value of approximately 230 nm to 260 nm. Analyzing the results, it can be concluded that the photoreduction of graphene oxide can be successfully carried out in different dispersants. Also, the photoreduction of silver chloride was successfully performed, and the presence of nanosilver was confirmed by the appearance of an absorbance maximum at a wavelength of 420 nm.
