Polymer quantum dots for luminescent solar concentrators

Carbon quantum dots (C-QDs) have attracted significant interest due to their adjustable opticalproperties, high quantum yield, strong photostability, low toxicity, and straightforward synthesismethods. Photoluminescent polyethylene glycol (PEG)-anchored carbon nitride dots, a type of CQDs,were successfully prepared via a one-step hydrothermal process. These polymer quantum dots(PDs) possess tunable diameters and exhibit excitation-dependent photoluminescent (PL) behavior.The PL mechanism of the PDs was determined to involve a single excited state, as confirmed byexcitation with a xenon lamp. The PDs demonstrate absorption and emission spectra ranging from۰۲۲ to ۰۲۲ nm and ۰۰۲ to ۰۲۲ nm, respectively. This research highlights the potential of PDs aspromising luminescent materials for applications in luminescent solar concentrators (LSCs).
