Abstract

Experimental data are presented on the study of a colloidal solution created through zinc ablation in water by means of high-power radiation from a copper vapor laser. Absorption spectrum analysis is performed in the optical range of λ = 200–600 nm. The structural composition and morphology of the solid phase isolated from the colloid are determined by means of X-ray diffractometry, and atomic-force and scanning electron microscopy. It is demonstrated that ZnO, as well as zinc, nanoparticles, which oxidize to ZnO under colloid ageing, are present in the colloid composition after target irradiation. The ZnO end product has a complex structure, which is based on hexagonal crystals 40 × 80 nm in size on average.
