报告大纲：

Novel photoluminescence (PL)  composite nanofibers (NFs) consist of carbon qunatum dots (CQDs) and fabricated  by the electrospinning process. The air-dried CQDs containing NFs were  characterized by field-emission scanning electron microscopy (FESEM),  transmission electron microscopy (TEM), fourier transform infrared spectroscopy  (FTIR), X-ray photoelectron spectroscopy (XPS), UV-visible spectroscopy,  spectrofluorometer, and confocal microscopy. CQDs are familiar to emit blue,  green and red color depending on the excitation energy. The CQDs decorated NFs  were found to be optically transparent and exhibited PL properties similar to  CQDs. Therefore, blue, green and red color was observed under confocal  microscope from the NFs membrane while the sample was excited by 405 nm, 488 nm  and 543 nm lasers. The results indicated the well preserved quantum confinement  properties of the CQDs inside the polymer matrix without aggregation or  substantial quantum dots growth.
