- Abstract
Atomic single-bubble sonoluminescence of Yb in a colloidal suspension in dodecane of SiO2 nanoparticles containing YbCl3 was recorded for the first time. A spectrum, containing lines of Yb, Yb+ in the area of 300–550 nm together with lines of SiO was obtained, which is conditioned by the entry of nanoparticles into the bubble during sonolysis of the suspension. The lower limit of determination of ytterbium in the initial water solution of YbCl3 applied for deposition on the nanoparticles constitutes 3 × 10–3 mol/L by the intensity of analytical line of 399 nm in the given spectrum. Comparison of the experimental and temperature-dependent calculated spectra of ytterbium allowed determining electron temperature in a nonequilibrium plasma appearing as a result of bubble collapsing, where Yb atoms emit light: Te = 7000 ± 500 K.
