PERBANDINGAN SIFAT OPTIK CDOTS BERBAHAN DAUN BINAHONG (ANREDERA SCANDES L.) SEGAR DAN KERING MENGGUNAKAN METODE BOTTOM UP

Carbon dots (Cdots) are synthesizable nanoparticles. One of them is taking advantage binahong leaves (Anredera scandes L.). In this research, the synthesis Cdots fresh and dried has been carried out. Using buttom up method UV-Vis characterization. Microwave heating for 30 minutes. Meanwhile, physical properties resulting color Binahong showing a yellowish green color, while dry show brownish color. light absorbance spectrum at wavelength 200-800 nm with highest intensity measured 323 energy value band gap 1.503 Ev. Cdots, have absorption 361 an 8.231 Ev gap.
