Carbon　particles　were　synthesized　in　aqueous　solution　of　the　biological　reagents　D-(+)-glucosamine-HCl　and　glucose.　The　structure　and　composition　of　synthesized　carbon　particles　were　investigated　using　field　emission　scanning　electron　microscope,　high-resolution　transmission　electron　microscope,　micro-Raman　spectroscope　and　Fourier　transform　infrared　spectroscope.　The　results　indicate　that　the　carbon　particles　are　formed　in　the　spherical　shape　and　amorphous　structure　with　diameter　of　0.3-1.4　μm.　The　photoluminescence　(PL)　of　carbon　particles　were　studied　in　micro-Raman　spectroscopy　using　the　325　nm　line　of　He-Cd　laser.　The　PL　spectra　show　a　weak　blue　PL　band　centered　at　420　nm　and　two　strong　and　wide　green　and　red　PL　bands　centered　at　575　and　650　nm,　which　are　related　to　the　functional　groups　and　the　transition　between　two　bands.　The　broadening　of　green　and　red　PL　bands　is　related　to　the　diversity　of　sp2　clusters.　©,　2015,　Chines　Academy　of　Sciences.　All　right　reserved.
