Jj. Wang et al., The comparative study on diamond film by near-field Raman spectroscopy andmicro-Raman spectroscopy, SOL ST COMM, 115(4), 2000, pp. 173-177
By combining a Dilor XY Raman spectrograph with a homemade scanning near-fi
eld optical microscope, we studied the near-field Raman spectrum of a diamo
nd film prepared by hot filament chemical vapor deposition. Several quite d
ifferent nearfield Raman spectra were observed in different positions of a
diamond film. The results were compared with micro-Raman spectra at the sam
e positions. We found the top layer of the film gave more contribution to t
he near-field Raman spectra. (C) 2000 Published by Elsevier Science Ltd. Al
