Modulation to sonoluminescence achieved in presence of carbon nano-dots in water

Researchers led by Prof. Xu Wen from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, along with their collaborators from Chongqing Medical University, recently investigated the influence of carbon nanodots (CNDs) on sonoluminescence effect, and they found that the color of sonoluminescence driven by intense ultrasound could be altered from ultraviolet-blue in water into orange by the presence of CNDs in water.
