Findings from City University of Hong Kong Yields New Findings on Alkenes [Poly(ethylene glycol)/carbon quantum dot composite solid films exhibiting intense and tunable blue-red emission]

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Alkenes. According to news reporting from Hong Kong, People's Republic of China, by NewsRx journalists, research stated, "Although carbon quantum dots (CQDs) possess excellent luminescence properties, it is a challenge to apply water-soluble CQDs to tunable luminescent devices."

The news correspondents obtained a quote from the research from the City University of Hong Kong, "Herein, quaternary CQDs are incorporated into poly(ethylene glycol) to produce poly(ethylene glycol)/CQD composite solid films which exhibit strong and tunable blue-red emission. The fluorescent quantum yield reaches 12.6% which is comparable to that of many liquid CQDs and the photoluminescence characteristics are determined to elucidate the fluorescence mechanism."

According to the news reporters, the research concluded: "The CQD solid films with tunable optical properties bode well for photoelectric devices especially displays."
