    Abstract

    This paper outlines new approaches for utilizing X-rays for gold nanoparticles deposition by performing Surface Photochemistry Induced by X- ray Irradiation (SPIXI). High-energy synchrotron radiation was used to induce the deposition of gold nanoparticles from a gold-salt solution onto di®erent sur- faces. By controlling the deposition parameters (dose, solution, surfactants, and stabilizer polymer concentrations), the distribution and average size of the nanoparticles can be in°uenced. The distribution of the deposited parti- cle heights and diameters at low doses suggests there is a mechanism of growth of the particles after nucleation on the surface.
