Abstract

AbstractThe preparation and sonoluminescence of Cr(CO)_6 nanodispersed suspensions in water, 83% H_2SO_4, and 74% H_3PO_4 are described for the first time. In the spectra of single- and multibubble sonoluminescence of these suspensions, chromium atom lines are found that are analogous to the corresponding lines in the sonoluminescence spectra of true Cr(CO)_6 solutions in dodecane. Sonoluminescence of nanodispersed suspensions of metal carbonyl, by which the electronic temperature reached in the bubbles under sonolysis (from 6500 to 16 000 K in water and acids) was measured, expands the scope of the sonochemical model of injection of nanodroplets of low volatile compounds into cavitation bubbles due to the inclusion of injection of suspensions of insoluble substances into it.
