“…It has recently been shown that characteristic spectra (bands) of molecular SL also arise during the sonolysis of luminophore organic solutions, such as simple benzene derivatives 19 or more complex polyaromatic molecules. 20 Undoubtedly, all the described cases of SL can be used for the luminescent spectroscopic determination of the corresponding compounds. But so far, this method has been most advanced (and discussed below) for the analysis of such elements as metals in aqueous solutions, whose characteristic SL spectra are obtained using multibubble sonolysis that usually occurs under the influence of immersed waveguides.…”

A brief research review is done on the new method development for the element luminescent determination, namely, sonoluminescent spectroscopy. The advantages and disadvantages of the technique of multibubble sonoluminescence (MBSL) in solutions used to apply this method are discussed. It has been shown that the use of a new technique moving single-bubble sonoluminescence (m-SBSL) in colloidal suspensions of nanoparticles (less than 50 nm) containing the elements analyzed seems preferable for this purpose. This makes it possible to determine elements not only at lower concentrations than when using MBSL in solutions, but also to find elements that are unavailable for determination through previous technique. Thus, the new technique expands the range of elements determined by sonoluminescent spectroscopy. The article provides a detailed description of the standard procedure for the preparation and recording of m-SBSL in colloidal suspensions, as well as examples of characteristic spectra of some elements obtained and recorded for the first time according to this new technique (Al, K, Mn, Cd, Pt, Ni, Ti), including those not previously found using the MBSL in solutions (Al, Cd, Pt, Ni, Ti). By the example of the analytical line at 396 nm in the Al spectrum obtained through the new technique on the basis of the AlCl3 initial aqueous solution, the region of the linear dependence of the intensity on the AlCl3 concentration was registered, and the lower limit of the spectroscopic determination of the Al content in this solution was estimated as 8.3·10–3 mol/L. Using the analysis of the obtained Cd spectrum as an example, we carried out a spectroscopic measurement of the electronic temperature achieved at m-SBSL in bubble plasma at the moments of the greatest compression of a bubble with light emission during its acoustic oscillations in dodecane Te = 7900 ± 500 K.

“…2 ) [6], органических люминофоров [7]. Несомненно, что все эти случаи СЛ пригодны для люминесцентного определения соответствующих соединений, но пока данный метод наиболее развит для анализа элементов -металлов, атомарные спектры которых до недавнего времени получали лишь с помощью техники многопузырьковой сонолюминесценции (МПСЛ) в растворах [1,2].…”

For the first time, atomic single-bubble sonoluminescence of Yb in a colloidal suspension in dodecane of SiO2 nanoparticles containing YbCl3 was recorded. A spectrum was obtained containing Yb, Yb+ lines in the region of 300-550 nm, together with SiO lines, due to the entry of nanoparticles into the bubble during sonolysis of the suspension. The lower limit of determination of ytterbium in the initial aqueous solution of YbCl3 used for depositing onto nanoparticles, according to the intensity of the analytical line at 399 nm in this spectrum, is 3∙10–3 mol/l. By comparing the experimental and temperature-dependent calculated spectra of ytterbium, we found the electron temperature in the nonequilibrium plasma that arises during bubble collapse, where Yb atoms emit light: Te = 7000±500 K.
