Ceramic Nanostructures Obtained by Acoustoplasma Technique

In this study, plasma discharge in a liquid in an intense ultrasonic field above the cavitation threshold has been proven to be of great interest for initiating various physical and chemical processes. In such a discharge, nanoparticles of tungsten and zinc oxides have been synthesized. Further exploration of synthesized nanoparticles has demonstrated that the factor of ultrasonic cavitation during the synthesis substantially affects the physical and chemical characteristics of nanoparticles. An important feature is the pronounced difference between the luminescence intensity of the particles obtained without ultrasonic treatment and the particles obtained in plasma under ultrasonic treatment: the higher intensity of particle luminescence in the case of ultrasonic action during the synthesis can be attributed to the numerous defects in the crystal structure and may be advantageous in view of possible applications for creating optically active materials.
