All N-Ti[O.sub.2] had high photoabsorption
capacity in the range of UV light to visible light, and the number of photo-generated electrons and holes to participate in the photocatalytic reaction was increased; additionally, the significant narrowing of the band gap is of great importance for practical applications of N-Ti[O.sub.2] since N-Ti[O.sub.2] can be activated by sunlight (Table 1).
Firstly, the Ti[O.sub.2-x][N.sub.x] nanorods sample presents a similar photocatalytic performance with the sample of Ti[O.sub.2-x][N.sub.x] nanoparticles even though the photoabsorption
efficiency of the former is obviously lower than that of the latter.
In an earlier publication-where we studied [CO.sub.2] photoionization with an electron spectrometer resolution of about 19 meV, members of the ([v.sub.1],0,2) p rogression were clearly visible (16] which indicates that the asymmetric stretch excitations can play a role in the photoabsorption
Therefore, the size-dependent 3C-SiC nanoparticles played an important role in photoabsorption
in the UV to visible spectral regions.
Based on the absorption (not shown here) and excitation spectra (Figure 3), it is found that the [M.sub.3][V.sub.2][O.sub.8] phosphor exhibits photoabsorption
ability from UV to visible light regions.

of the fullerene [C.sub.60] and its positive ions.
Also shown are the three principal contributions to the cross section, namely elastic scattering, inelastic scattering, and photoabsorption
. For carbon, inelastic scattering is seen in Fig.
Energy resolution (AE) is defined as [DELTA]E = FWHM/[Ch.sub.peak], where FWHM and [Ch.sub.peak] represent the full-width at half-maximum (FWHM) and the peak channel of the photoabsorption
peak in pulse-height spectrum, respectively.
The crystal structure and symmetry determine that at least two distinct diamagnetic ODCs can form in Si[O.sub.2] and they are commonly denoted as ODC(I) and ODC(II), giving rise to the photoabsorption
bands at ~7.6 and ~5.0 eV, respectively [4, 11].
