Strong luminescence carbon nanodots by green synthesis based microwave assisted from fruit peel

Green synthesis carbon nanodots (CDs) based microwave assisted in fruit peels, orange and banana peel, was performed using the green synthesis based microwave assisted. The existence of CDs evidenced by results of photoluminescence, the absorbance of Ultraviolet-Visible light, and molecular bonds with Fourier Transform Infra-Red (FTIR ) spectroscopy. Synthesized CDs of fruit peel has a strong luminescence with absorbance wavelengths 286 nm and 319 nm from orange peel and 284 nm from banana peel which indicated luminescence of CNs dominated from the surface state. This results supported by PL data that shows the wavelength intensity of CDs orange peel at 498 nm and CDs banana peel at 501 nm . The advantages of green synthesis based microwave assisted are CDs particle stable and homogeneous. This means the method applied here efficiently for synthesis CDs from fruit peel. (paper)
