Figure 4

PL emission spectra of the colloidal cubic SiC nanocrystals. Room temperature PL spectra of 3C-SiC nanocrystals dispersed in (a) ethanol and (b) water. (c) The PL emission spectra of colloidal cubic SiC nanocrystals in water and ethanol solutions at the excitation wavelength of 320 nm (the insert is two emission photos taken using a Canon digital camera at the same excitation wavelength).
