We report room temperature single photon emission from optical emitters in zinc oxide (ZnO) nanoparticles formed using ion implantation and thermal oxidation in a silica substrate.
X-ray emission induced by high-flux 60 keV negative Cu ion implantation into silica glasses (a-SiO2) has been studied in an energy range of 0.6 – 20 keV. At low ion fluxes, the emission spectrum consists of a strong Cu(L) line at 0.95 keV only, without Cu(K) and Si(K) lines. The result is explained by the electron promotion through the quasi-molecule… (More)

Using methods of electronic and atomic-force microscopy, energy-dispersive analysis, laser scanning microscopy, X-ray diffraction, hardness measurements the nitrides of high-entropy alloys (TiZrAlYNb)N, obtained by cathodic-vacuum-arc-vapor-deposition, were investigated. Influence of residual gas pressure on the properties of investigated nitrides was… (More)
Ion-flux dependent nanoparticle formation is observed in silica glasses under high-flux 60 keV Cu<sup>−</sup> implantation. Under the high-flux implantation, a strong electric field possibly forms in the glass, and may affect the nanoparticle formation via the solute diffusion processes. In this paper, the internal-field formation is evaluated based… (More)
In this paper we present two examples of combining fluorescent nanoparticles with photonic materials. First, we present the results on new compound: nanodiamonds and silk. Second, we report on ZnO fluorescence, with ZnO nanoparticles obtained by Zn-ion implantation in silica.
