The results of a comparative study of the optical properties of the thin films of zinc oxide ZnO, taking into account the influence of their copper doping, are presented. Using the experimental spectra of optical transmission, spectral dependences of the refractive and extinction index of the studied material, as well as components of complex dielectric permittivity constant, were calculated. The revealed features of the obtained dispersion curves are associated with the behavior of the impurity injected into the ZnO matrix. Keywords: zinc oxide, optical transmission, refractive index, dielectric permittivity.

Pulsed laser ablation in liquid (PLAL) of metallic magnesium was used in this work to manufacture magnesium nanoparticles with varying average sizes (10–90[Formula: see text]nm). (2.07–3.44) [Formula: see text] 108[Formula: see text]W/cm2 of laser intensity and pulse rates of 100 pulses were used to create the nanoparticles. Laser power increased the number of nanoparticles in magnesium oxide (MgO) at 204[Formula: see text]nm absorption spectroscopic absorbance linearly. When the UV–Vis absorbance of nanoparticles rose, so did their colloidal density (measured in mg/mL). Nanoparticles are more likely to be produced at higher laser scanning rates: UV–Vis absorbance and nanoparticle diameters. Field emission scanning electron microscopy (FESEM) revealed that nanoparticles created dendritic patterns when put upon metal foil. The nanoparticles were measured using dynamic light scattering. When MgO particles were used in antibacterial activity against (in vitro) various gram-positive and gram-negative strains of bacteria, they had a demonstrable impact on some strains of bacteria. MgO has been shown to have antibacterial properties.
