Synthesis of Photoluminescent Carbon Nanoparticles by Hydrothermal Method

Carbon nanoparticles were synthesized via hydrothermal oxidation of glucose.The carbon dots were characterized by X-ray diffraction( XRD),transmission electron microscopy( TEM), ultraviolet-visible spectrophotometry,fluorescene spectrophotometry and Fourier transform infrared spectrophoto-metry( FTIR).The results indicate that the carbon dots have appropriate spherical morphology,uniform size,good dispersion,non-agglomeration.The carbon dots can emit bright green photoluminescence under UV excitation,and exhibit excitation-dependent PL behavior.
