Bougainvillea Spectabilis

Synthesized carbon dots (CDs) from paper flowers (Bougainvillea spectabilis) was performed by microwave assisted. CDs were characterized by ultraviolet visible light (UV-Vis), photoluminescence (PL) and time resolved luminescence (TRPL). PL data shows wavelength intensity of CDs paper flowers at 493 nm for 3.9 ns and 512 nm for 4.2 ns respectively for purple and white paper flowers that excited at 420 nm. The absorbance for CDs white paper flower at 262 nm and 350 nm, while CDs purple flower paper at 260 nm, 324 nm, and 530 nm. CDs from paper flower shows excellent optical properties. So, it is mean that method applied to this experiment effectively, cheap and eco-friendly for synthesis CDs from paper flower.

Herein, a rapid microwave assisted solid state method is reported for the synthesis of highly fluorescent N-doped carbon dots (NCDs) using citric acid as carbon source and guanidine hydrochloride as N-dopant. Synthetic parameters such as microwave power, irradiation time and reactants ratio were optimized to produce high quality N-doped carbon dots. The N-doped carbon dots were well characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), SEM-EDS, FTIR, UV-visible and fluorescence spectroscopies. N-Doped carbon dots exhibited bright emission with a quantum yield of 11 %. Detailed study of their optical properties revealed their excellent property of resistance to photo bleaching, high ionic strength and solution pH. Further they exhibited excitation dependent emission behaviour, high aqueous solubility and a long shelf life of 60 days. This strong fluorescence emission combined with high stability make N-doped carbon dots a promising fluorescent probe for wide range of applications.
