Raman spectroscopy was used to study the back surface of a free-standing diamond film deposited by chemical vapour deposition. Two techniques, Raman mapping and Raman imaging, were employed; their relative merits are discussed. A 40 mu m x 40 mu m square region of surface was studied using Raman scattered light from the various forms of carbon, and light from the 1.68 eV diamond luminescence band. The maps and images reveal information about the composition and stress of the film over distance scales comparable with the diamond grain size. For example, regions of higher quality diamond (i.e. giving a narrow, intense diamond 1332 cm(-1) peak) could be seen to be surrounded by regions of a more graphitic nature. The results illustrate the great potential of Raman mapping and Raman imaging for revealing the detailed structure of diamond films.
