Sonoluminescence of aqueous solution of luminol-sodium carbonate

The image of a preset papercut figure taken with ordinary film exposed to the sonoluminescenceof aqueous solution of Luminol-Sodium carbonate, the sonoluminescence spectrum and photoexcitative fluorescence spectrum of this solution obtained by the authors show that the wavelengths of the enhanced sonoluminescence by luminol in this solution are mainly in the visible region. In respect to emission wave-lengths, there is a certain equivalency between sonoexcitation and photexcitation.
