Photoluminescence (PL) composite nanofibers (NFs) consist of carbon qunatum dots (CQDs) and Poly(ethylene oxide) (PEO) were fabricated by the electrospinning process. The air-dried CQDs containing NFs were characterized by field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), fourier transform-infrared spectroscopy (FT-IR), UV-visible spectroscopy, spectrofluorometry, and confocal microscopy. CQDs are familiar to emit blue, green and red color depending on the excitation energy. The PEO/CQDs NFs were found to be optically transparent and exhibited PL properties similar to CQDs. |
