Studies from Xiamen University in the Area of Luminescence Described

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Luminescence. According to news originating from Xiamen, People's Republic of China, by NewsRx correspondents, research stated, "Optically tunable carbon dots (CDs) were fabricated through a simple one-step microwave-assisted procedure. These carbonaceous nanoparticles exhibited tunable emission under a single wavelength excitation, controllable size without any tedious separation process and stabilities towards photobleaching and high ionic strength."

Our news journalists obtained a quote from the research from Xiamen University, "The effects of size difference and surface property on the fluorescence behaviors of CDs were explored through a post-reduction/oxidation method. Experimental results also demonstrated the fluorescence of CDs could be tuned when exposed to H2O2/AcOH solutions. Moreover, the use of as-synthesized CDs as a chemical sensor for the quantification of hypochlorous acid (HClO) has been preliminarily tested, showing high sensitivity and selectivity towards HClO over other common ions."

According to the news editors, the research concluded: "The superior optical properties would enable the use of CDs in multiplexed optical coding of biomolecules, light-emitting devices and biological applications."
