We report the novel thermal quenching of carbon nanodots (CNDs), synthesized by a simple solvothermal method. The emission energy and intensity of the CND samples can be tuned by thermal annealing at varying temperatures in an ambient atmosphere, attributed to the varying fractions of the core sp2 moiety and the surrounding surface chemical groups. While the as-synthesized samples show a positive...
Amorphous carbon films with different surface topologies were synthesized on a Si substrate by plasma enhanced chemical vapor deposition at various pressures using acetylene as a carbon precursor. The samples were characterized by scanning electron microscopy, atomic force microscopy and Fourier transformed infrared spectroscopy. The contact angles for water with the as-prepared carbon films were...
