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 m. 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 sp
