    LUMINESCENCE CARBON NANOPARTICLES FROM SOOT
    (UNIVERSITY OF LAGOS, 2015) Omoogun, A.; Igbinehi, J.; Fagbenro-Owoseni, K.; Nejo, O.; AbdulWahab, K.O.; Igbari, O.; Adams, L.A.
    Carbon nanoparticles (CNPs) were extracted from kerosene; diesel and petrol soot using a medium containing a mixture of acetone and water. TheCNPs showed green and blue luminescence under 365nm UV light and were further characterized using SEM, UVvisible spectroscopy and FT-IR. The UV-visible spectra of the CNPs showed absorption maxima corresponding to blue shift and also attributable to non-uniform distribution. The SEM indicated that the CNPs occurred in aggregate structure with average size estimated to be about 40 nm. The FT-IR showed the presence of pure carbon without evidence of any functionalization.
