For optical measurements, 10 mg of nanoparticle powder was dispersed in distilled water to prepare the solution for transmittance spectra recording. The transmittance spectra of the material were recorded using a Specord 210 Plus spectrophotometer in the wavelength range of 200-900 nm. The results were obtained as .xlsx files using the corresponding software.Ministry of Education and Science of Ukraine0124U000541
