Resumo
The results of the synthesis of nanoclusters of metallic zinc and its oxide in crystalline quartz implanted with 64Zn+ ions with a dose of 5 × 1016 cm–2 and energy of 40 keV and annealed in an oxygen atmosphere in the temperature range 400–900°C are presented. Scanning electron microscopy combined with energy-dispersive spectroscopy, as well as Auger electron spectroscopy and photoluminescence, were used for the study. After implantation, separate nanoclusters of metallic zinc with a size of less than 1 µm were fixed on the surface and in the near-surface layer of quartz. It was established that, during annealing, the sample underwent a transition from the phase of metallic Zn to the phases of its oxide ZnO and silicate Zn2SiO4. After annealing at 700°C, which is the most optimal for obtaining the ZnO phase, zinc oxide nanoclusters smaller than 500 nm in size were formed in the near-surface layer of quartz. A peak in the form of a doublet at a wavelength of 370 nm was observed in the photoluminescence spectrum due to exciton luminescence in zinc oxide. After annealing at 800°C, the ZnO phase degraded and the zinc silicate phase Zn2SiO4 was formed.
