Abstract: The adsorption of allyl alcohol on chemical vapour deposited (CVD) diamond thin film has been studied with high resolution electron energy loss spectroscopy (HREELS) and X-ray absorption near edge spectroscopy (XANES). Our results suggest allyl alcohol readily adsorbs on pre-annealed CVD diamond. There are differences in the reactivity of allyl alcohol on sputtered diamond surfaces compared to pristine clean surfaces. The strong increase in C{double bond, long}C π* signal following the adsorption of allyl alcohol on freshly sputtered diamond suggests the possibility of spontaneous dissociation into allylic η3-C3H5 and OH on defects. The increase in C{double bond, long}C π* signal is weaker on pristine diamond, due possibly to the [2 + 2] type cycloaddition reactions of allyl alcohol which break the π bonds. XANES study shows that adsorption of allyl alcohol promotes the total electron yield from the CVD diamond surface. © 2006 Elsevier B.V. All rights reserved.
