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.
